Heuristic outcome (STATUS_UNKNOWN) of transaction not handled properly
----------------------------------------------------------------------

                 Key: JBCACHE-1167
                 URL: http://jira.jboss.com/jira/browse/JBCACHE-1167
             Project: JBoss Cache
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 1.4.1.SP4, 2.0.0.GA
            Reporter: Galder Zamarreno
         Assigned To: Manik Surtani
             Fix For: 1.4.1.SP5

Where an XA transaction has a heuristic outcome, the status reported to 
the afterCompletion synchronization is STATUS_UNKNOWN (5), since 
JTA does not handle heuristics. In this case, the cache Synchronization 
fails to rollback the cache tx. This leaves the app server in a bad (i.e. locked) 
state even though the XA transaction has been resolved. 

At first glance it looks like the afterCompletion synchronization should treat a 
STATUS_UNKNOWN as a cause for rollback as well as logging the error as 
they currently do. Unfortunately the fix may be more complex than that, since 
the db may have committed rather than rolled back, meaning the cache would 
be out of sync with the db if you rolled it back.
