[i dont think, this is coming because of a transaction being marked as rollback, because if thats the case, the exception would have contained already marked for rollback msg] [and i dont think this is coming because of time out, since logs didnt contain timed out msg, [i experimented this by setting small time out for a transaction, logs showed msg about it. so only saying this]] -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/780420#780420] Start a new discussion in IronJacamar at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
