[jboss-jira] [JBoss JIRA] (WFLY-6319) NPE in LocalEjbReceiver.removeClusterNodes during server shutdown

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: Dmitrii Tikhomirov 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}}: {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 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.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) {code} This happens during server shutdown, so it probably doesn't affect anything.
