--------------------------------------

             Summary: IllegalStateException when patching MBeans are queried during shutdown
                 Key: WFLY-3505
                 URL: https://issues.jboss.org/browse/WFLY-3505
             Project: WildFly
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Patching
    Affects Versions: 8.1.0.Final
            Reporter: James Livingston
            Assignee: Emanuel Muckenhuber
         Attachments: shutdownmbeanquery.jar

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.
