- * does not create a new instance, it will force it to go through an initialization
- * cycle which includes a "pause" at the beginning of proecessing. We just must

+ *
+ * They will run successfully when you run all of them under runAllTests(),
+ * however, you will get all sorts of non-fatal errors in the log and on the
+ * console that result from overlapping threads that are not terminated at the
+ * end of each test. The problem is that the JUnit environment does not terminate
+ * all the test threads between tests. This is true even if you break each JUnit
+ * into a separate file. Consequently, all the tests would have to be refactored
+ * so all test object initializations are coordinated. In other words, you
+ * retrieve the ActiveStandbyFeature instance and other class instances only once
+ * at the beginning of the JUnits and then reuse them throughout the tests.
+ * Initialization of the state of the objects is pretty straight forward as it
+ * just amounts to manipulating the entries in StateManagementEntity and
+ * DroolsPdpEntity tables. However, some thought needs to be given to how to
+ * "pause" the processing in ActiveStandbyFeature class. I think we could "pause"
+ * it by calling globalInit() which will, I think, restart it. So long as it
+ * does not create a new instance, it will force it to go through an initialization
+ * cycle which includes a "pause" at the beginning of proecessing. We just must
+ * be sure it does not create another instance - which may mean we need to add
+ * a factory interface instead of calling the constructor directly.
