------------------------------------

             Summary: Participants should not be told to compensate after completion
                 Key: JBTM-2977
                 URL: https://issues.jboss.org/browse/JBTM-2977
             Project: JBoss Transaction Manager
          Issue Type: Bug
          Components: LRA
    Affects Versions: 5.7.1.Final
            Reporter: Nicola Ferraro
            Assignee: Michael Musgrove


When a LRA is closed the coordinator behaves incorrectly if a participant is slow to respond.

While the call to "/complete" is still ongoing, the coordinator (recovery module) may issue a second call to "/compensate", making it impossible for the participant to determine when a LRA is really closed.

The LRA coordinator must choose a single outcome for the LRA and be consistent with that (retrying until all participants are in status complete/failedtocomplete in this case).

A second minor problem is that the call to "/close" is synchronous, and the caller is kept attached forever if the participant does not respond to "/complete". It would be better to establish a timeout and return a "Completing" status if not all participant are done in time.

I attach few simple steps to reproduce it with shell commands.
