SyslogTest.canReceiveSyslogMessages() failed with AMQ classloader error

Description

I saw a failure in SyslogTest.canReceiveSyslogMessages() at appears to be a race condition while refreshing the bundles on startup of the Minion container:

Exception in thread "ActiveMQ InactivityMonitor WriteCheckTimer" java.lang.NoClassDefFoundError: org/apache/activemq/transport/AbstractInactivityMonitor$3 at org.apache.activemq.transport.AbstractInactivityMonitor.writeCheck(AbstractInactivityMonitor.java:158) at org.apache.activemq.transport.AbstractInactivityMonitor$2.run(AbstractInactivityMonitor.java:122) at org.apache.activemq.thread.SchedulerTimerTask.run(SchedulerTimerTask.java:33) at java.util.TimerThread.mainLoop(Timer.java:555) at java.util.TimerThread.run(Timer.java:505) Caused by: java.lang.ClassNotFoundException: Unable to load class 'org.apache.activemq.transport.AbstractInactivityMonitor$3' because the bundle wiring for org.apache.activemq.activemq-osgi is no longer valid. at org.apache.felix.framework.BundleWiringImpl.findClassOrResourceByDelegation(BundleWiringImpl.java:1539) at org.apache.felix.framework.BundleWiringImpl.access$400(BundleWiringImpl.java:79) at org.apache.felix.framework.BundleWiringImpl$BundleClassLoader.loadClass(BundleWiringImpl.java:2018) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 5 more

This might be caused because we aren't shutting down ActiveMQ completely whenever the blueprint contexts refresh. I'll check on this behavior.

The inactivity timers might also be involved in bug https://opennms.atlassian.net/browse/NMS-8714#icft=NMS-8714.

Gonna mark this as fixed since I think it was resolved by refreshing the bundles fewer times on startup.

I haven't seen this particular error in a while and it is likely less of an issue since Jesse changed the Karaf extender so that bundles are only refreshed once instead of multiple times when the Minion starts up. Reducing priority.

Occurred again on Bamboo today.
