problem :
TaskServiceSession.taskOperation() catches RuntimeException and if transactionType == local-JTA, sets the UserTransaction to Status.MARKED_ROLLBACK.  However, in the finally block, a ut.commit() is currently ALWAYS invoked.  Attempting to commit on a trnx marked for rollback is an illegal operation.  Subsequently, the original RuntimException is overwritten by a new RuntimeException as follows (in a bitronix environment .... a similar runtime exception is thrown by arjuna in JBoss) :

java.lang.RuntimeException: bitronix.tm.internal.BitronixRollbackException: transaction was marked as rollback only and has been rolled back




solution :
modify the finally block in TaskServiceSession.taskOperation() :

446 if (transactionStarted) {
447     try {
448         UserTransaction ut = (UserTransaction)new InitialContext().lookup( "java:comp/UserTransaction" );
449         if(ut.getStatus() !=javax.transaction.Status.STATUS_MARKED_ROLLBACK)
450             ut.commit();
451     } catch (Exception e) {
452         throw new RuntimeException(e);
453     }       
454 }
