    Description

      In a failover test that passivates sessions to a SQL database (though I think this isn't really relevant much), I've seen a NPE in LocalEjbReceiver.removeClusterNodes:

      04:09:29,330 WARN  [org.jboss.msc.service.fail] (MSC service thread 1-6) MSC000004: Failure during stop of service jboss.ejb3.localEjbReceiver.value: java.lang.NullPointerException

	at org.jboss.as.ejb3.remote.LocalEjbReceiver.disassociate(LocalEjbReceiver.java:681)
	at org.jboss.ejb.client.EJBClientContext.unregisterEJBReceiver(EJBClientContext.java:446)

	at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617)
	at java.lang.Thread.run(Thread.java:745)

      This happens during server shutdown, so it probably doesn't affect anything.

          • Blocker - To be worked above all other priorities. This term is chosen when the severity of the issue is very high, has no workaround, or the effort for the change is comparatively low. Issues that may be very publicly visible and could generate significant media attention may also drive a higher priority.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
