Alexandre Gattiker commented on AS7-4962:
-----------------------------------------

Thank you Clebert, I've updated the bug description accordingly. The RuntimeException allows to detect the issue though, because re-deliveries create a delay that causes the Arquillian test in the project attached to undeploy the MDB while re-deliveries are still in progress.
