      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.removeClusterNodes(LocalEjbReceiver.java:701)
      	at org.jboss.as.ejb3.remote.LocalEjbReceiver.disassociate(LocalEjbReceiver.java:681)
      	at org.jboss.ejb.client.EJBClientContext.unregisterEJBReceiver(EJBClientContext.java:446)
      	at org.jboss.ejb.client.EJBReceiverContext.close(EJBReceiverContext.java:57)
      	at org.jboss.as.ejb3.remote.LocalEjbReceiver.stop(LocalEjbReceiver.java:410)
      	at org.jboss.msc.service.ServiceControllerImpl$StopTask.stopService(ServiceControllerImpl.java:2056)
      	at org.jboss.msc.service.ServiceControllerImpl$StopTask.run(ServiceControllerImpl.java:2017)

      	at java.lang.Thread.run(Thread.java:745)
      

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