Messaging replication fails to check-for-live-server on restart --------------------------------------------------------------- Key: WFLY-5762 URL: https://issues.jboss.org/browse/WFLY-5762 Project: WildFly Issue Type: Bug Components: JMS Affects Versions: 10.0.0.CR4 Reporter: Jeff Mesnil Assignee: Andy Taylor Priority: Major Fix For: 10.0.0.CR5 The attached configuration use JGroups. I had a look at the code and I suspect the issue is located somewhere when the server1 is restarted and calls its SharedNothingLiveActivation#isNodeIdUsed(). This method returns false and the server completes its live activation instead of setting its HA policy to replicaPolicy. Digging into the code, I looks like DiscoveryGroup#received boolean is never set to true because its corresponding JGroupsBroadcastEndpoint never receives any JGroups message. I confirm that server2 is working at that time and does send JGroups message. I suspect that there is a bug in the wrapping of JGroups receiver/channel/etc. in org.apache.activemq.artemis.api.core.JGroupsBroadcastEndpoint and the endpoint in DiscoveryGroup never receives the message that is actually received by JGroups in the ReceiverAdapter instantiated by JGroupsBroadcastEndpoint.JChannelWrapper#connect.
