On WildFly clean shutdown: failed marshalling rsp (UnsuccessfulResponse) ------------------------------------------------------------------------ Key: WFLY-2845 URL: https://issues.jboss.org/browse/WFLY-2845 Project: WildFly Issue Type: Bug Components: Clustering Affects Versions: 8.0.0.CR1 Environment: RHEL6 x86_64; Oracle JDK 7 Reporter: Michal Karm Babacek Assignee: Paul Ferraro Labels: clustering Fix For: 10.1.0.Final I've got two standalone-ha instances running on a one box. Each of these instances has {{<distributable/>}} [clusterbench|https://github.com/Karm/clusterbench/tree/simplified-and-pure] app deployed. When I start to shut the instances down via CLI command, one of them throws: {noformat} 08:59:33,341 INFO [org.infinispan.remoting.transport.jgroups.JGroupsTransport] (Incoming-4,shared=udp) ISPN000094: Received new cluster view: [jboss-eap-8.0/web|4] (1) [jboss-eap-8.0/web] 08:59:33,368 INFO [org.infinispan.remoting.transport.jgroups.JGroupsTransport] (MSC service thread 1-8) ISPN000082: Stopping the RpcDispatcher 08:59:33,379 ERROR [org.jgroups.blocks.RequestCorrelator] (remote-thread-0) failed marshalling rsp (UnsuccessfulResponse): java.lang.NullPointerException 08:59:33,380 ERROR [org.jgroups.blocks.RequestCorrelator] (remote-thread-1) failed marshalling rsp (UnsuccessfulResponse): java.lang.NullPointerException 08:59:33,392 INFO [org.jboss.as] (MSC service thread 1-1) JBAS015950: WildFly 8.0.0.Final-SNAPSHOT "WildFly" stopped in 558ms {noformat} In the log. It's a non-deterministic problem and it does not emerge always.
