Hello,

I'm using LocalTaskService inside an EJB CMT.

Problem is, whenever TaskService generates an error, it tries to rollback the transaction calling ut.rollback() instead of ut.setRollbackOnly().

So, the original exception is swallowed and instead I get 

Caused by: java.lang.IllegalStateException: JBAS014160: Tx erroné pour cette chaîne : TransactionImple < ac, BasicAction: 0:ffff0affce14:-23020732:512359da:43 status: ActionStatus.ABORTED > attendu, mais avons null

I think there's an error in org.jbpm.task.service.TaskServiceSession, lien 462, takeOverTransaction should be false when we're running inside an EJB CMT.

} catch (RuntimeException re) {
    
    // We may not be the tx owner -- but something has gone wrong.
    // ..which is why we make ourselves owner, and roll the tx back. 
    boolean takeOverTransaction = true;
    tpm.rollBackTransaction(takeOverTransaction);
 
 
    doOperationInTransaction(new TransactedOperation() {
        public void doOperation() {
            task.getTaskData().setStatus(Status.Error);
        }
    });
 
 
    throw re;
} 


I'll update this thread whenever I'll have more info.

Can someone confirm this is a bug in jBPM ?

Thanks
