Doc Text:	This release of JBoss EAP 6 carries a bug caused by the patching subsystem PatchResource not having a depenency on the InstallationManagerService but using it when it may be shut down. This may cause an `IllegalStateException` if a shutdown hook attempts to query the patching subsystem MBeans. The workaround is to confirm whether the `InstallationManagerService` is up prior to using it.	Story Points:	---

Description James Livingston 2014-07-17 06:23:28 UTC

If the MBeans for the patching subsystem are queried during server shutdown, it can result in an IllegalStateException. InstallationManagerService has already had stop() called on it, so the value is null.

This can be reproduced by the attached EJB, which does a MBeanServer.queryMBeans(null, null); from the @PreDestroy method. It's in a loop to ensure it runs after the installation manager gets de-initialised.
