             Summary: NPE in LocalEjbReceiver.removeClusterNodes during server shutdown
                 Key: WFLY-6319
                 URL: https://issues.jboss.org/browse/WFLY-6319
             Project: WildFly
          Issue Type: Bug
          Components: Clustering, EJB
            Reporter: Ladislav Thon
            Assignee: Paul Ferraro


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

{code}
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 java.lang.Thread.run(Thread.java:745)
{code}

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