[jboss-jira] [JBoss JIRA] Updated: (BPEL-260) Flow activity might not reactivate parent token in race condition

[ http://jira.jboss.com/jira/browse/BPEL-260?page=all ] Alejandro Guizar updated BPEL-260: ---------------------------------- Description: The flow activity suffers from the same problem as the join node in jPDL. When child tokens complete the nested activities concurrently, it is possible that all of them determine that the parent token must not be reactivated yet, leading to deadlock. The cause of this behavior is transaction isolation. To prevent this problem, the code to leave the flow must acquire exclusive access to the state of the concurrent tokens. was: The flow activity suffers from the same problem as the join node in jPDL.
