These should succeed and > the RMApp state machine should transition to completed like normal. > Unregistration should succeed for an app that the RM considers complete since > the RM may have died after saving completion in the store but before > notifying the AM that the AM is free to exit. -- This message was sent by Atlassian JIRA (v6.2#6252)
