Michal Vinkler created WFLY-10274: ------------------------------------- Summary: NPE during server shutdown when using scattered cache Key: WFLY-10274 URL: https://issues.jboss.org/browse/WFLY-10274 Project: WildFly Issue Type: Bug Components: Clustering Affects Versions: 13.0.0.Beta1 Reporter: Michal Vinkler Assignee: Paul Ferraro We hit NPE when running tests for RFE EAP7-867. EAP distribution was built from https://github.com/pferraro/wildfly/tree/scattered . Test description: Positive stress test (no failover), 4-node EAP cluster, clients: starting with 400 clients in the beginning, raising the number of clients to 6000 in the end of the test. During clean server shutdown in the end of the test, server logged NPE and got stuck: {code} [JBossINF] [0m[31m07:55:57,643 ERROR [org.infinispan.scattered.impl.ScatteredStateConsumerImpl] (thread-200,ejb,dev214) ISPN000471: Failed processing values received from remote node during rebalance.: java.lang.NullPointerException [JBossINF] at org.infinispan.scattered.impl.ScatteredStateConsumerImpl.applyValues(ScatteredStateConsumerImpl.java:505) [JBossINF] at org.infinispan.scattered.impl.ScatteredStateConsumerImpl.lambda$getValuesAndApply$8(ScatteredStateConsumerImpl.java:475) [JBossINF] at java.util.concurrent.CompletableFuture.uniWhenComplete(CompletableFuture.java:760) [JBossINF] at java.util.concurrent.CompletableFuture$UniWhenComplete.tryFire(CompletableFuture.java:736) [JBossINF] at java.util.concurrent.CompletableFuture.postComplete(CompletableFuture.java:474) [JBossINF] at java.util.concurrent.CompletableFuture.complete(CompletableFuture.java:1962) [JBossINF] at org.infinispan.remoting.transport.AbstractRequest.complete(AbstractRequest.java:66) [JBossINF] at org.infinispan.remoting.transport.impl.SingleTargetRequest.receiveResponse(SingleTargetRequest.java:56) [JBossINF] at org.infinispan.remoting.transport.impl.SingleTargetRequest.onResponse(SingleTargetRequest.java:35) [JBossINF] at org.infinispan.remoting.transport.impl.RequestRepository.addResponse(RequestRepository.java:53) [JBossINF] at org.infinispan.remoting.transport.jgroups.JGroupsTransport.processResponse(JGroupsTransport.java:1304) [JBossINF] at org.infinispan.remoting.transport.jgroups.JGroupsTransport.processMessage(JGroupsTransport.java:1207) [JBossINF] at org.infinispan.remoting.transport.jgroups.JGroupsTransport.access$200(JGroupsTransport.java:123) [JBossINF] at org.infinispan.remoting.transport.jgroups.JGroupsTransport$ChannelCallbacks.receive(JGroupsTransport.java:1342) [JBossINF] at org.jgroups.JChannel.up(JChannel.java:819) [JBossINF] at org.jgroups.fork.ForkProtocolStack.up(ForkProtocolStack.java:134) [JBossINF] at org.jgroups.stack.Protocol.up(Protocol.java:340) [JBossINF] at org.jgroups.protocols.FORK.up(FORK.java:134) [JBossINF] at org.jgroups.protocols.FRAG3.up(FRAG3.java:166) [JBossINF] at org.jgroups.protocols.FlowControl.up(FlowControl.java:343) [JBossINF] at org.jgroups.protocols.FlowControl.up(FlowControl.java:343) [JBossINF] at org.jgroups.protocols.pbcast.GMS.up(GMS.java:864) [JBossINF] at org.jgroups.protocols.pbcast.STABLE.up(STABLE.java:240) [JBossINF] at org.jgroups.protocols.UNICAST3.deliverMessage(UNICAST3.java:1002) [JBossINF] at org.jgroups.protocols.UNICAST3.handleDataReceived(UNICAST3.java:728) [JBossINF] at org.jgroups.protocols.UNICAST3.up(UNICAST3.java:383) [JBossINF] at org.jgroups.protocols.pbcast.NAKACK2.up(NAKACK2.java:600) [JBossINF] at org.jgroups.protocols.VERIFY_SUSPECT.up(VERIFY_SUSPECT.java:119) [JBossINF] at org.jgroups.protocols.FD_ALL.up(FD_ALL.java:199) [JBossINF] at org.jgroups.protocols.FD_SOCK.up(FD_SOCK.java:252) [JBossINF] at org.jgroups.protocols.MERGE3.up(MERGE3.java:276) [JBossINF] at org.jgroups.protocols.Discovery.up(Discovery.java:267) [JBossINF] at org.jgroups.protocols.TP.passMessageUp(TP.java:1248) [JBossINF] at org.jgroups.util.SubmitToThreadPool$SingleMessageHandler.run(SubmitToThreadPool.java:87) [JBossINF] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) [JBossINF] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) [JBossINF] at org.jboss.as.clustering.jgroups.ClassLoaderThreadFactory.lambda$newThread$0(ClassLoaderThreadFactory.java:52) [JBossINF] at java.lang.Thread.run(Thread.java:748) [JBossINF] {code} Server link: https://jenkins.hosts.mwqe.eng.bos.redhat.com/hudson/job/eap-7x-stress-se... -- This message was sent by Atlassian JIRA (v7.5.0#75005)
