[jboss-jira] [JBoss JIRA] (WFLY-4672) Possible trouble of exception cause during error of 2PC

Possible trouble of exception cause during error of 2PC ------------------------------------------------------- Key: WFLY-4672 URL: https://issues.jboss.org/browse/WFLY-4672 Project: WildFly Issue Type: Bug Components: Remoting, Transactions Affects Versions: 10.0.0.Alpha1 Reporter: Ondřej Chaloupka Assignee: Ondřej Chaloupka I have test scenario where crash recovery of transaction is tested. I have two XA resources which process commit - meaning to 2PC. Sometimes during the commit connection to database is put down which causes the 2PC does not finish successfully. # Enlist Test XA # Enlist DB XA # Prepare Test XA # Prepare DB XA # Commit Test XA # Connection to DB is interrupted/closed # Commit DB XA # Exception is thrown and got by client There is issue in type of transaction that is returned back to client. For {{EAP6}} it was (for JTA) {{java.rmi.RemoteException}} caused by {{javax.ejb.EJBException}} caused by {{javax.transaction.HeuristicMixedException}} If user does {{txn.commit()}} (or container did it on itself when CMT is used) and the problem described above occurs then user can got cause information that transaction failed as heuristic. For WFLY the situation changed. I can see that exception in the {{server.log}} is enhanced by {{suppressed}} exception and this one is returned as cause to client. The example of such exception stack trace is here {code} 2015-05-25 13:36:41,226 ERROR [org.jboss.as.ejb3.invocation] (EJB default - 4) WFLYEJB0034: EJB Invocation failed on component JPACrashBean for
