APAR status

• Closed as program error.

Error description

• When a third-party JMS Provider is failed over, an application
  running in WebSphere under a JTA transaction with a single
  resource throws an HeuristicHazardException and the following
  messages are logged in the SystemOut.log

  ****************************************************************
  A JMS Provider was used in a JTA Transaction with no other
  resources.  When such a transaction commits, it will use a
  one-phase commit.  If the JMS Provider throws a
  javax.jms.TransactionRolledBackException, for example if the
  JMS Provider failed over before the commit, this results in a
  javax.transaction.HeuristicMixedException on the commit.
  This behaviour is expected by default, however if the JVM
  system property
  "com.ibm.ws.j2c.XARBonLocalTransactionException" is set to
  true, as per APAR PM81105, then a
  javax.transaction.RollbackException is expected.  Due to
  incorrect handling of the TransactionRolledBackException a
  HeuristicMixedException was thrown on the commit regardless of
  the system property value.
  

Problem conclusion

• The handling of the TransactionRolledBackException by the
  messaging component was modified so that the correct exception
  was thrown.
  
  
  The fix for this APAR is targeted for inclusion in fix pack
  9.0.5.7 For more information, see 'Recommended Updates for
  WebSphere Application Server':
