The StandbyStateManagementTest.testPMStandbyStateChangeNotifier() test failed due to an assertion failure.  Looking at the log, it appears that the test is reusing a StateManagement instance because an existing IntegrityMonitor is present due to creation of the instance of a state management feature in a previous test.  This is not a problem for other tests, but in this case, the test relies on the Standby Status previous value.  For this test, the value is incorrect.  The solution is to simply create a fresh instance of the StateManagement class and use it directly rather than create an instance of the feature for StateManagement.
