[jboss-jira] [JBoss JIRA] (WFLY-8243) Clustered Singleton MDB does not activate

Clustered Singleton MDB does not activate ----------------------------------------- Key: WFLY-8243 URL: https://issues.jboss.org/browse/WFLY-8243 Project: WildFly Issue Type: Bug Components: Clustering, EJB, JMS Reporter: Flavia Rainone Assignee: Flavia Rainone Priority: Blocker Clustered Singleton MDB does not activate. It's regression in EAP 7.1.0.DR8 (against DR7). Customer impact: No Clustered Singleton MDB will activate in cluster and service will not operate. No warning or error will show in server logs. There is no workaround for this issue. Test scenario: - Start two EAP 7.1.0.DR8 servers in cluster with active delivery-group named "group" - Deploy queues InQueue and OutQueue to both of the servers. There is also Artemis cluster configured between servers so all messages will be load-balanced between the nodes. - Deploy MDB configured as clustered singletons to both of the server. MDBs belong to delivery-group "group" -- MDB consumes messages from InQueue and resends to OutQueue - Start sending messages to InQueue and consume from OutQueue. - Check that MDB on node 1 is active as it's sigleton master - Check that MDB on node 2 is NOT active - Kill node-1 (by kill -9 ...) - Check that MDB on node 2 is active as it's sigleton master Expected result: Consumer will receive all messages from OutQueue. All checks passes. Actual result: MDB on node 1 is not delivery active at the beginning of the test. Consumer timed out as there are no processed messages in OutQueue
