+/**
+ * Apex parameters for JMS as an event carrier technology.
+ * <p>
+ * The parameters for this plugin are:
+ * <ol>
+ * <li>initialContextFactory: JMS uses a naming {@link Context} object to look up the locations of JMS servers and JMS
+ * topics. An Initial Context Factory is used to when creating a {@link Context} object that can be used for JMS
+ * lookups. The value of this parameter is passed to the {@link Context} with the label
+ * {@link Context#INITIAL_CONTEXT_FACTORY}. Its value must be the full canonical path to a class that implements the
+ * {@code javax.naming.spi.InitialContextFactory} interface. The parameter defaults to the string value
+ * {@code org.jboss.naming.remote.client.InitialContextFactory}.
+ * <li>providerURL: The location of the server to use for naming context lookups. The value of this parameter is passed
+ * to the {@link Context} with the label {@link Context#PROVIDER_URL}. Its value must be a URL that identifies the JMS
+ * naming server. The parameter defaults to the string value {@code remote://localhost:4447}.
+ * <li>securityPrincipal: The user name to use for JMS access. The value of this parameter is passed to the
+ * {@link Context} with the label {@link Context#SECURITY_PRINCIPAL}. Its value must be the user name of a user defined
+ * on the JMS server. The parameter defaults to the string value {@code userid}.
+ * <li>securityCredentials:The password to use for JMS access. The value of this parameter is passed to the
+ * {@link Context} with the label {@link Context#SECURITY_CREDENTIALS}. Its value must be the password of a suer defined
+ * on the JMS server. The parameter defaults to the string value {@code password}.
+ * <li>connectionFactory: JMS uses a {@link javax.jms.ConnectionFactory} instance to create connections towards a JMS
+ * server. The connection factory to use is held in the JMS {@link Context} object. This parameter specifies the label
+ * to use to look up the {@link javax.jms.ConnectionFactory} instance from the JMS {@link Context}.
+ * <li>producerTopic: JMS uses a {@link javax.jms.Topic} instance to for sending and receiving messages. The topic to
+ * use for sending events to JMS from an Apex producer is held in the JMS {@link Context} object. This parameter
+ * specifies the label to use to look up the {@link javax.jms.Topic} instance in the JMS {@link Context} for the JMS
+ * server. The topic must, of course, also be defined on the JMS server. The parameter defaults to the string value
+ * {@code apex-out}.
+ * <li>consumerTopic: The topic to use for receiving events from JMS in an Apex consumer is held in the JMS
+ * {@link Context} object. This parameter specifies the label to use to look up the {@link javax.jms.Topic} instance in
+ * the JMS {@link Context} for the JMS server. The topic must, of course, also be defined on the JMS server. The
+ * parameter defaults to the string value {@code apex-in}.
+ * <li>consumerWaitTime: The amount of milliseconds a JMS consumer should wait between checks of its thread execution
+ * status. The parameter defaults to the long value {@code 100}.
+ * <li>objectMessageSending: A flag that indicates whether Apex producers should send JMS messages as
+ * {@link javax.jms.ObjectMessage} instances for java objects (value {@code true}) or as {@link javax.jms.TextMessage}
+ * instances for strings (value {@code false}) . The parameter defaults to the boolean value {@code true}.
+ * </ol>
