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
