+/**
+ * This class is used to synchronize signaling of status between threads.
+ * <p>
+ * In complex multi-threaded applications it is often necessary to synchronize operations between threads. This is
+ * especially true in complex algorithms where processing dependencies exist between different threads and the
+ * synchronization of the operations of those threads is required. This class is a framework to enable multi-thread
+ * signaling and wait/post logic that makes the thread synchronization easier.
+ * </p>
+ * <p>
+ * Basically, in thread synchronization, one thread is the "waiter" and one or more other threads are the "notifiers".
+ * The notifiers send signals to the waiter to inform that thread that certain conditions are true, processing has been
+ * completed, or to inform the waiter of the state of the other thread(s). In the basic java framework, the waiter and
+ * notifier are simply using the wait/notify mechanism provided, which does not allow for different conditions, state,
+ * or "signals" to exist. The wait/notify mechanism, in combination with the object mutex, provides basic blocking and
+ * releasing of a thread's dispatching state.
+ * </p>
+ * <p>
+ * This class builds upon the java wait/notify mechanism and allows for "signals" to be defined. These signals are
+ * simply string constants that mean something to the waiter and notifier threads. Any number of signals may be defined,
+ * and it is possible to wait for more than one signal to be received, wait for any one of a set to be received, or to
+ * test if a signal has been received without blocking.
+ * </p>
+ * <p>
+ * Some operations are blocking operations. These stop the execution of the calling thread until the specified condition
+ * is true. These blocking methods are all named "wait...", such as {@link #waitFor(String...)} and
+ * {@link #waitForAny(String...)}. The thread making the call to these blocking methods MUST be the waiter thread (the
+ * thread registered with the signal object).
+ * </p>
+ * <p>
+ * Some operations are non-blocking. These operations allow for the testing or setting of signal conditions and do not
+ * block the caller. When calling these methods ({@link #isSignaled(String)}, {@link #signal(String)}, and
+ * {@link #setTimeout(long)} the waiter thread mutex will be held and may block the waiter thread for the duration of
+ * the method call.
+ * </p>

+/**
+ * The configuration factory is used to obtain access to an already created and initialized
+ * singleton configuration object as well as to create and initialize the singleton if not already
+ * set up.
+ * <p>
+ * This class is responsible for the creation of the configuration object used to manage the
+ * configuration of the application. The configuration object implementation must implement the
+ * <code>Configuration</code> interface. This allows for the factory to create different
+ * specializations in the future if needed and not break any application code.
+ * </p>
+ * <p>
+ * The configuration object is basically a wrapper around a properties object. The configuration is
+ * therefore specified as a set of properties that are loaded and processed from different sources
+ * with different precedences. It is important that the configuration object always be able to
+ * supply default values for any configuration properties that must be supplied, and not rely on the
+ * user always supplying these values. This also relieves the application itself from having to
+ * interpret missing or invalid properties and applying defaults. By having all of the defaults in
+ * one place, the application code can be simpler (not having to worry about defaults or invalid
+ * properties), and the defaults can be changed much easier (they are all in one place and not
+ * distributed throughout the codebase).
+ * </p>
+ * <p>
+ * Since the configuration is managed as a property object, we can use a characteristic of the
+ * <code>Properties</code> class to our advantage. Namely, if we put a property into a
+ * <code>Properties</code> object that already exists, the <code>Properties</code> object replaces
+ * it with the new value. This does not affect any other properties that may already be defined in
+ * the properties object. This gives us the ability to initialize the properties with default values
+ * for all of the application settings, then override just those that we need to override, possibly
+ * from multiple sources and in increasing order of precedence.
+ * </p>
+ * <p>
+ * This means that properties are in effect "merged" together from multiple sources in a prescribed
+ * precedence order. In fact, the precedence order that this factory implements is defined as:
+ * </p>
+ * <ol>
+ * <li>Default values from a system resource file.</li>
+ * <li>User-supplied properties file, if any.</li>
+ * <li>Application-supplied properties, if any.</li>
+ * <li>Command-line properties (if any)</li>
+ * </ol>
+ * <p>
+ * The name and location of the properties file that is loaded can also be set, either in the
+ * defaults, overridden by the system command line via -D, or as a system environment variable.
+ * There are two properties that can be specified to define the name and path. These are:
+ * </p>
+ * <dl>
+ * <dt>org.onap.appc.bootstrap.file</dt>
+ * <dd>This property defines the name of the file that will be loaded. If not specified, the default
+ * value is "appc.properties". This can be specified in either (or both) the default properties or
+ * the command line. The command line specification will always override.</dd>
+ * <dt>org.onap.appc.bootstrap.path</dt>
+ * <dd>This is a comma-delimited (,) path of directories to be searched to locate the specified
+ * file. The first occurrence of the file is the one loaded, and no additional searching is
+ * performed. The path can be specified in either, or both, the default values and the command line
+ * specification. If specified on the command line, the value overrides the default values. If
+ * omitted, the default path is <code>$/opt/onap/appc/data/properties,${user.home},.</code></dd>
+ * </dl>

+<title>Configuration</title>
+</head>
+
+<body>
+  <p style="margin-left: 30.0px;">
+    CDP Configuration support is provided by a common framework to load
+    and manage configuration properties from multiple sources. The basic
+    concept is to load a set of default properties from a known resource
+    file located on the class path, and then override these defaults
+    with optional settings that can be provided by a user through either
+    additional property files or via the command line (as VM arguments).
+    The loading of defaults from a resource property file (named <strong>com/att/cdp/default.properties</strong>)
+    ensures that values are defined for properties the application needs
+    in order to operate.
+  </p>
+  <p style="margin-left: 30.0px;">
+    One of these default values that can be set is the name of the
+    property file that allows the user to supply settings, as well as
+    the path where the file can be found. In general, the default name
+    of the property file will be &quot;<strong>cdp.properties</strong>&quot;,
+    and the path that will be searched is &quot;<strong>${user.home};etc;../etc</strong>&quot;.
+    However, these values can be changed through the use of the
+    default.properties resource file. The property that specifies the
+    property file name is named <strong>com.att.cdp.bootstrap.file</strong>,
+    while the property named <strong>com.att.cdp.bootstrap.path</strong>
+    specifies the search path.
+  </p>
+  <p style="margin-left: 30.0px;">
+    After the default.properties are loaded, but prior to searching for
+    the application configuration file, the configuration factory checks
+    for properties <strong>com.att.cdp.bootstrap.path</strong> and <strong>com.att.cdp.bootstrap.file
+    </strong>in the System properties object (meaning they were set by the
+    command line). If these values are defined in the system properties
+    object, they are used. If not, these values are obtained from the
+    default properties just loaded. This allows the specification of
+    either the file name or path, or both, to be overridden during start
+    up by using command-line arguments.
+  </p>
+  <p style="margin-left: 30.0px;">The search path is scanned for the
+    first occurrence of the specified property file. The first
+    occurrence is loaded and scanning is stopped at that point. The
+    configuration factory does not load all occurrences it finds, only
+    the first occurrence it finds.</p>
+  <p style="margin-left: 30.0px;">The configuration properties are
+    loaded and processed according to a defined precedence order, such
+    that properties defined with a higher precedence override the same
+    property at a lower precedence. The precedence order is defined as
+    follows:</p>
+  <h2>Precedence Order</h2>
+  <ol>
+    <li>Default properties are initially loaded into the
+      configuration. These default properties are the lowest level
+      precedence, and will be overridden by any properties specified at
+      higher levels. These are loaded from resources that are packaged
+      as part of the various application components. Each component
+      (Server, Coordinator, EPM, or CLI) may have different default
+      properties. The default properties are loaded from a resource
+      named <strong>com/att/cdp/default.properties</strong>. The default
+      properties can specify the name of the application property file
+      to be used to configure the application, as well as the path to
+      search. Additionally, these properties can be supplied via the
+      command line to override the default settings if needed.<br /> <br />
+    </li>
+    <li>The configuration factory allows for the application to
+      supply an initial properties object to initialize the
+      configuration. This properties object could be loaded or created
+      in any way necessary for the application. This is totally up to
+      the application to define, if it is needed. If no
+      application-specific property object is supplied, this step is
+      skipped. If a property object is supplied, it is used to replace
+      or set any properties that may have been defined by the defaults.<br />
+      <br />
+    </li>
+    <li>The configuration factory will then search for a bootstrap
+      file on a bootstrap path. The actual bootstrap file name and path
+      can be specified as properties on the command line, or will
+      default to a file name of <strong>cdp.properties</strong> and a
+      path of <strong>${user.home};etc;../etc</strong>. If desired, the
+      user can specify the exact name of the property file to be loaded
+      as well as the path using <strong>-Dcom.att.cdp.bootstrap.file=&lt;filename&gt;</strong>
+      and <strong>-Dcom.att.cdp.bootstrap.path=&lt;path&gt;</strong>.
+      These properties are set to default values by the default
+      properties loaded in step #1 above. The first occurrence of a
+      property file is the file loaded and used. Any other occurrences
+      are not processed.<br /> <br />
+    </li>
+    <li>The System properties are then merged into the
+      configuration. This allows the highest level of precedence,
+      command-line VM arguments (-D<strong>name=value</strong>) to be
+      merged into the configuration property object. These settings
+      override all lower level settings of the same name, as well as
+      merge all system properties into the configuration object.
+    </li>
+  </ol>
+  <h2>Variables</h2>
+  <p style="margin-left: 30.0px;">
+    The configuration support allows for variables to be inserted into
+    any property that is defined. Variables are named using the format <strong>${name}</strong>,
+    where the &quot;name&quot; is the name of a property that is defined
+    in the configuration, or a system property (such as <strong>user.home</strong>).
+    Variables can nest, such that a variable can be replaced with
+    another variable, which is then reevaluated to obtain the value.
+    This allows for indirection as well as variable substitution, if
+    needed.
+  </p>
+  <h2>Using the Configuration Support</h2>
+  <p style="margin-left: 30.0px;">
+    The configuration support was designed to be easy to use. The
+    configuration implementation is abstracted away from the application
+    so that it could be changed easily in the future if needed, or if we
+    needed to load different implementations for different reasons. This
+    means that the application always accesses the configuration through
+    an interface, named <strong>Configuration</strong>. The
+    implementation of that configuration interface is obtained by a
+    static method on the <strong>ConfigurationFactory</strong> class.
+    The configuration factory will both create the configuration if not
+    already created on the first access, as well as return the current
+    configuration if already created. Additionally, the
+    ConfigurationFactory provides mechanisms to recreate the
+    configuration after the application is initialized should the need
+    arise to update its configuration.
+  </p>
+  <p style="margin-left: 30.0px;">An example of the code needed to
+    obtain access to the configuration is:</p>
+  <pre style="margin-left: 30.0px;">Configuration config = ConfigurationFactory.getConfiguration();</pre>
+  <p style="margin-left: 30.0px;">Please refer to the javadoc or the
+    source code in cdp-common for other ways that the configuration and
+    configuration factory can be used.</p>
+  <h2>Reloading Properties</h2>
+  <p style="margin-left: 30.0px;">The configuration support allows
+    for properties to be re-loaded and re-evaluated after the
+    application is running. This is designed to allow a configuration to
+    be refreshed should the need arise. This could allow on-demand
+    refresh (via a command, for example), or automatically based on
+    sensing a change in the configuration file.</p>
+  <p style="margin-left: 30.0px;">
+    When the <strong>ConfigurationFactory</strong> method <strong>getConfiguration(Propert</strong><strong>ies)</strong>
+    is called, the current configuration is cleared and rebuilt using
+    the process defined above. The supplied property object is used in
+    step #2 of the process. While the properties are being re-built, no
+    access to the properties are allowed. Any attempt to access
+    properties while the re-build operation is in effect will block the
+    caller until completed. This is accomplished using read and write
+    shared locks.
+  </p>

+CONFIGURATION_STARTED=APPC0001I|\
+  ECOMP Application Controller (APP-C) initialization started at {0}|\
+  No resolution is required, this is an informational message|\
+  The APP-C component configuration has been started because the component is being \
+    initialized or loaded for the first time, or a new instance of the component is \
+    being created.  This message indicates that the component is starting.
+
+CONFIGURATION_CLEARED=APPC0002I|\
+  All prior configuration has been cleared|\
+  No resolution is required, this is an informational message|\
+  The APP-C component is being started or restarted and any prior configuration \
+    (if present), is cleared.  This is normal.
+
+LOADING_CONFIGURATION_OVERRIDES=APPC0003I|\
+  Loading configuration properties from file "{0}"|\
+  No resolution is required, this is an informational message|\
+  This message indicates that the configuration of the APP-C component was located \
+    and is being loaded from the specified file.
+
+LOADING_DEFAULTS=APPC0004I|\
+  Configuration defaults loaded from resource file "{0}"|\
+  No resolution is required, this is an informational message|\
+  This is a normal indication that the default configuration settings were loaded \
+    from the resource file.  The APP-C components load a default configuration first \
+    so that all configuration values have valid default settings.  Any user configuation \
+    that may be specified then overrides these defaults.
+
+NO_DEFAULTS_FOUND=APPC0005E|\
+  No default property resource "{0}" was found!|\
+  This is an internal error.  Contact support.|\
+  This is an internal error that indicates that the default resource property file \
+    could not be located.  This is likely a packaging error and is indicative of \
+    a construction problem.  Refer this to development or level 3 support for assistance.
+
+PROPERTY_VALUE=APPC0006I|\
+  Property "{0}" ="{1}"|\
+  No resolution is required, this is an informational message|\
+  This message is issued to show the value of configuration properties and is used to \
+    debug start up of the component.
+
+NO_OVERRIDE_PROPERTY_FILE_LOADED=APPC0007E|\
+  No configuration file named [{0}] was found on the configuration search path [{1}]. \
+    If a configuration file should have been loaded, check the file name and search \
+    path specified.  APPC will proceed using the default values and command-line \
+    overrides (if any).|\
+  If a configuration file was expected, verify the file name and that it exists on \
+    the search path for the configuration properties.  The search path defaults to \
+    <em>&#36;{user.home},/opt/app/appc/etc,etc,../etc,/etc,.</em> and can be overridden \
+    by specification of the property <em>org.onap.appc.bootstrap.path</em>.  The \
+    property file name defaults to <em>appc.properties</em> and can also be \
+    overridden by the <em>org.onap.appc.bootstrap.file</em> property.|\
+  This message indicates that the bootstrap path was searched for the bootstrap \
+    property file (a file that can be supplied to configure APPC) and that no file \
+    with the specified name was found on any of the path elements of the path.
+
+SEARCHING_CONFIGURATION_OVERRIDES=APPC0008I|\
+  Searching path "{0}" for configuration settings "{1}"|\
+  No resolution is required|\
+  This message indicates that the specified path is being examined for a configuration \
+    file of the indicated name.  The configuration file defaults to <em>appc.properties</em> \
+    but can be overridden by specification of the <em>org.onap.appc.bootstrap.file</em> \
+    property (using a command-line override, for example).  This message is intended to \
+    assist in the debugging and analysis of configuration issues where the indicated \
+    file may not be processed or found.  The path that is searched is a comma-delimited \
+    list of directories and defaults to <em>&#36;{user.home},/opt/app/appc/etc,etc,../etc,/etc,.</em> \
+    but can also be overridden by specification of the <em>org.onap.appc.bootstrap.path</em> \
+    property.
+
+LOADING_APPLICATION_OVERRIDES=APPC0009I|\
+  Loading application-specific override properties|\
+  No resolution required|\
+  This message indicates that the APPC component was invoked as an embedded component \
+    and that the caller has supplied an override property object.
+
+NO_APPLICATION_OVERRIDES=APPC0010I|\
+  No application-specific override properties were provided!|\
+  No resolution required|\
+  This message indicates that the APPC component was invoked as an embedded component \
+    and that the caller has supplied an override property object, but that object was \
+    empty.
+
+MERGING_SYSTEM_PROPERTIES=APPC0011I|\
+  Merging system properties into configuration|\
+  No resolution is required|\
+  This message indicates that the java virtual machine system properties are being \
+    examined and merged into the APP-C component configuration.  This allows for command \
+    line specification of any APP-C configuration property as a standard java define \
+    JVM option (ex: -Dproperty=value).
+
+SETTING_SPECIAL_PROPERTY=APPC0012I|\
+  Setting property "{0}={1}" in system properties|\
+  No resolution required.|\
+  This message indicates that the specified property loaded from defaults, property \
+    file overrides, application overrides, or command-line overrides is being placed \
+    in the system (java virtual machine) properties object.  Some libraries that may \
+    be integrated with APP-C (for example, DME2 or AFT libraries) may only look for \
+    their properties in the system properties object.  This allows those components \
+    to be configured from the APP-C configuration.
+
+LOADING_RESOURCE_BUNDLE=APPC0013I|\
+  Loading resource bundle "{0}"|\
+  No resolution required|\
+  This message indicates that the specified resource bundle is being loaded.
+
+LOGGING_ALREADY_INITIALIZED=APPC0014W|\
+  Logging has already been initialized, check the container logging definitions to ensure \
+    they represent your desired logging configuration.|\
+  If logging is configured incorrectly, move the definitions to the container or component \
+    that first initialized logging.  If they are ok, no resolution is required.|\
+  This message indicates that the logging environment already exists and has been configured.
+
+SEARCHING_LOG_CONFIGURATION=APPC0015I|\
+  Searching path "{0}" for log configuration file "{1}"|\
+  No resolution is required|\
+  This message indicates that the APP-C component configuration file specified a logging \
+    configuration file and/or search path and the path is being searched.  This is used to \
+    assist in debugging the configuration process.
+
+LOADING_DEFAULT_LOG_CONFIGURATION=APPC0016I|\
+  Loading default logging configuration from system resource file "{0}"|\
+  No resolution is required|\
+  A default logging configuration for the component is loaded from system resources to \
+    ensure that a valid logging environment exists.  This is a normal message, and will \
+    be followed by APPC0019I if a user-specified logging configuration overrides the \
+    defaults.
+
+NO_LOG_CONFIGURATION=APPC0017E|\
+  No log configuration could be found or defaulted!|\
+  A valid logging configuration cannot be found, and no default configuration resource \
+    was loaded.  This is likely a packaging issue and should be referred to development \
+    or level 3 support for assistance.|\
+  This is an internal error.
+
+UNSUPPORTED_LOGGING_FRAMEWORK=APPC0018E|\
+  An unsupported logging framework is bound to SLF4J.  Only Logback or Log4J are supported.|\
+  This is a compatibility error with logging frameworks used in the application environment \
+    and should be referred to development or level 3 support for assistance.|\
+  This is an internal error.
+
+LOADING_LOG_CONFIGURATION=APPC0019I|\
+  Loading logging configuration from file "{0}"|\
+  No resolution is required|\
+  The specified logging configuration is being loaded.
+
+UNKNOWN_PROVIDER=APPC0020E|\
+  Provider {0} cannot be found or cannot be resolved to one of the known providers, [{1}].|\
+  Specify the name of a valid provider. The IAAS adapter contains a set of providers \
+    that are defined.  Each of these providers is assigned a logical name.  The call \
+    to the IAAS adapter must specify the name of the provider that is desired.  This \
+    could be the result of an incorrect call, or the IAAS adapter configuration is \
+    wrong.|\
+  The APP-C IAAS adapter is being called to request a service on a specific provider, but \
+    the name of the provider cannot be found in the list of defined providers.  This may \
+    be an error in the directed graph that contains the call to the IAAS adapter, or it \
+    may be an error in the request, or the configuration of the IAAS adapter may need \
+    to be updated.
+
+SERVER_STATE_CHANGE_TIMEOUT=APPC0021E|\
+  Server name "{0}" with id "{1}" in tenant "{2}" and region "{3}" did not change state \
+    within the alloted time. Current state is "{4}" and the desired state(s) are "{5}"|\
+  This is likely a provider issue.  If the provider is OpenStack, check the virtual \
+    machine on the horizon dashboard.  If the machine is in an invalid state, you may \
+    need to contact Openstack support.  The exact mechanisms for recovery of a machine \
+    in an invalid state are varied and will be different from provider to provider.|\
+  This message indicates that the IAAS adapter has performed some requested action \
+    on the specified server (virtual machine) but the server did not enter a valid \
+    state (running, stopped, etc) within the timeout period.  The last state (current state) \
+    is shown, as well as the state that was expected.  The servers name, UUID, containing \
+    tenant, and region are shown so that the correct provider can be examined.
+
+SERVER_DELETED=APPC0022E|\
+  Server name "{0}" with id "{1}" in tenant "{2}" has a state of deleted and cannot be {3}.|\
+  The specified server has been deleted on the provider.  This is likely an incorrect \
+    request.  Make sure that you are specifying the correct server ID/name, provider, \
+    and region.  If the self-link URL is used, make sure that the correct server resource \
+    is specified.  If the machine was correct, recreate or rebuild the machine to make \
+    it usable.  Correct the request.|\
+  This message indicates that the server specified was found to have been deleted in the \
+    target provider and that the requested action cannot be performed.  This may be caused \
+    by several things:\
+    <ol>\
+      <li>The UUID of the server is wrong and specifies a machine that no longer exists</li>\
+      <li>The machine was deleted by a different process or request</li>\
+      <li>The wrong provider was requested</li>\
+      <li>The request was out-of-order</li>\
+    </ol>
+
+UNKNOWN_SERVER_STATE=APPC0023E|\
+  Server name "{0}" with id "{1}" in tenant "{2}" has an unknown state of "{3}".|\
+  Check the machine to determine the state of the machine.  Correct that state to a valid \
+    state if possible.  This may also be caused by an internal error in the PAL (Provider \
+    Abstraction Layer) used by the IAAS if a new state definition has been added to the \
+    provider (such as a new version or the installation of an unknown or unsupported \
+    extension).  If the machine's state is valid, refer this error to development or \
+    level 3 support for assistance.|\
+  This message indicates that a request was made to the IAAS adapter to take some action \
+    on the specified virtual machine, but the machine was found to be in a state that \
+    prevents that action from being performed.

+  Exception {0} was caught attempting {1} of server [{2}] on tenant [{3}]|\
+  Contact support for assistance|\
+  An exception was caught while trying to perform the indicated operation on the server. The \
+    exception may yield more information about the cause of the error.  This may be because \
+    of access security, or the server is in an invalid state, or any number of reasons.  This \
+    message should be referred to support for assistance.
+
+
+STACK_NOT_FOUND=APPC0043E|\
+  No stack found in provider with self-link URL [{0}]|\
+  Correct the server URL|\
+  The requested stack, identified by its self link URL, could not be found in the provider
+
+STACK_OPERATION_EXCEPTION=APPC0044E|\
+  Exception {0} was caught attempting {1} of server [{2}] on tenant [{3}]|\
+  Contact support for assistance|\
+  An exception was caught while trying to perform the indicated operation on the stack. The \
+    exception may yield more information about the cause of the error.  This may be because \

+IMAGE_NOT_FOUND=APPC0047E|\
+  The image {0} could not be located for {1}.|\
+  The image indicated could not be found.  If the operation being requested is a rebuild of \
+    a server, then there is no action that can be taken other than to destroy the server and \
+    rebuild it using an image that exists.|\
+  This is likely caused by an image being deleted after it was used to build a server.  If the \
+    request is for a server rebuild, then the image used to create the server was later deleted \
+    and no longer exists.  The server cannot be rebuilt, because the image doesnt exist. \
+    The server must be deleted and reconstructed using a valid, existing image.
+
+STATE_CHANGE_TIMEOUT=APPC0048E|\

+    retrying in {5} seconds, attempt {6} of {7}.|\
+  The connection to the provider could not be obtained for the indicated reason.  The application \
+    controller will retry the attempt to connect to the provider a maximum number of times.  The \
+    message contains the amount of time the system will wait to retry the connection, and the \
+    current attempt and the maximum number of attempts.|\
+  Correct the cause of the connection failure as indicated by the reason.
+
+CONNECTION_FAILED=APPC0055E|\
+ Connection to provider {0} at service {1} failed after all retry attempts.|\
+ The connection to the named provider at the indicated service URL cannot be opened.  All \
+   retries have been exhausted.  The application controller is giving up on the connection and will \
+   fail the request.|\
+ Correct the cause of the connection failure as indicated by the reason(s) in previous APPC0054E \
+   messages.
+
+STOPPING_SERVER=APPC0056I|\

+  The server rebuild failed for the indicated reason. Correct the cause of the failure and \
+    rerun, if applicable.|\
+  The adapter has attempted to rebuild the indicated server but the rebuild request has \
+    been failed by the provider for some reason.  The reason returned by the provider is \
+    included in the message.
+
+PARAMETER_IS_MISSING=APPC0058E|\
+  Application {0} graph {1} response did not set the {2} parameter. This parameter is \
+    required for synchronization with the controller. Absence of this parameter is assumed \
+    to be a failure. Please correct the DG.|\
+  The indicated directed graph was called from the application controller but when the \
+    graph returned the indicated property was not defined in the return parameters.  The \
+    controller requires that property to be defined and set to a value that is used to \
+    inform the controller of the outcome of operations in the graph.  Failure to set \
