When BridgeParticipantAT receives prepare, participant should associate current thread with corresponding JTA transaction
-------------------------------------------------------------------------------------------------------------------------

                 Key: JBTM-329
                 URL: http://jira.jboss.com/jira/browse/JBTM-329
             Project: JBoss Transaction Manager
          Issue Type: Bug
      Security Level: Public (Everyone can see)
         Environment: JBoss-4.2.1.GA, JBossTS-4.2.3.SP7
            Reporter: Pavel Kadlec


When participant receives prepare from coordinator, it calls prepare on jta transaction. SubordinateAtomicAction.doPrepare then calls beforeCompletion() method. Hibernate registers Synchronization object which is called in  beforeCompletion() method. In that synchronization object, when hibernate cannot find transaction on current thread, it flushes all entites into database, which is bad.
When Hibernate cannot find transaction on thread, it logs WARN  [AbstractEntityManagerImpl] Transaction not available on beforeCompletionPhase: assuming valid

Fix is easy, BridgeParticipantAT should associate current thread with the corresponding JTA transaction. And finally it should suspend that JTA transaction.
