infinispan exception during wildfly app server startup ------------------------------------------------------ Key: ISPN-7164 URL: https://issues.redhat.com/browse/ISPN-7164 Project: Infinispan Issue Type: Bug Environment: RHEL 7, VMWare ESX 5.5, Wildfly 8.2.1 cluster with 6 nodes Reporter: Purush Reddy Priority: Major We are seeing the following exception in the cluster node startup. Please note that this issue is sporadic. This seems like race condition. the application on one node is calling evictAll() before the other node (throwing the exception) fully starts up and initializes the region. 2016-10-26 17:57:56,606 ERROR [OOB-18,shared=udp]-[org.infinispan.remoting.InboundInvocationHandlerImpl] ISPN000260: Exception executing command: java.lang.NullPointerException at org.hibernate.cache.infinispan.util.EvictAllCommand.perform(EvictAllCommand.java:64) at org.infinispan.remoting.InboundInvocationHandlerImpl.handleInternal(InboundInvocationHandlerImpl.java:95) at org.infinispan.remoting.InboundInvocationHandlerImpl.handleWithWaitForBlocks(InboundInvocationHandlerImpl.java:186) at org.infinispan.remoting.InboundInvocationHandlerImpl.handle(InboundInvocationHandlerImpl.java:84) at org.infinispan.remoting.transport.jgroups.CommandAwareRpcDispatcher.executeCommandFromLocalCluster(CommandAwareRpcDispatcher.java:259) at org.infinispan.remoting.transport.jgroups.CommandAwareRpcDispatcher.handle(CommandAwareRpcDispatcher.java:211) at org.jgroups.blocks.RequestCorrelator.handleRequest(RequestCorrelator.java:460) at org.jgroups.blocks.RequestCorrelator.receiveMessage(RequestCorrelator.java:377) at org.jgroups.blocks.RequestCorrelator.receive(RequestCorrelator.java:247) at org.jgroups.blocks.MessageDispatcher$ProtocolAdapter.up(MessageDispatcher.java:667) at org.jgroups.blocks.mux.MuxUpHandler.up(MuxUpHandler.java:130) at org.jgroups.JChannel.up(JChannel.java:708) at org.jgroups.stack.ProtocolStack.up(ProtocolStack.java:1015) at org.jgroups.protocols.RSVP.up(RSVP.java:187) at org.jgroups.protocols.FRAG2.up(FRAG2.java:165) at org.jgroups.protocols.pbcast.GMS.up(GMS.java:1010) at org.jgroups.protocols.pbcast.STABLE.up(STABLE.java:234) at org.jgroups.protocols.UNICAST3.up(UNICAST3.java:391) at org.jgroups.protocols.pbcast.NAKACK2.handleMessage(NAKACK2.java:774) at org.jgroups.protocols.pbcast.NAKACK2.up(NAKACK2.java:570) at org.jgroups.protocols.VERIFY_SUSPECT.up(VERIFY_SUSPECT.java:147) at org.jgroups.protocols.FD_ALL.up(FD_ALL.java:185) at org.jgroups.protocols.FD_SOCK.up(FD_SOCK.java:301) at org.jgroups.protocols.MERGE3.up(MERGE3.java:303) at org.jgroups.protocols.Discovery.up(Discovery.java:379) at org.jgroups.protocols.TP$ProtocolAdapter.up(TP.java:2641) at org.jgroups.protocols.TP.passMessageUp(TP.java:1429) at org.jgroups.protocols.TP$MyHandler.run(TP.java:1615) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745)
