Just curious why the test AcknowledgeAfterFailoverOnMessageTest would be running at all. To me it looks like you've configured Jenkins to run the default test profile but yet the default profile excludes AcknowledgeAfterFailoverOnMessageTest citing
QPID-143 : Failover can occur between receive and ack but we don't stop the ack.
// Just fully disable both tests as they are highlighting to many Java Client race conditions
Am I missing the obvious?
I think getting a public CI server for this project would be a great step forward.
