We could create and could do task operations successfully. But now we include subtask strategy("onAllSubtasksEndParentTaskEndStrategy") also. Problem is that when we complete the tsubtask, the below exception is thrown. Please help... I passed knowledge session to workitem handler as mentioned in another discussion. java.lang.IllegalStateException: EntityManager is closed 17:57:42,007 INFO  [LoggingFilter] SENT: HeapBuffer[pos=0
