  Anybody has any clue.   What I have noted is though above exception is comming my workflow get completed successully. What I think two different thread trying to access same data , one successufully updates the data and which is why the workflow gets completed , but the other one keeps retrying for many times.  Please let me know any solution to such race condition. Thanks. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/636462#636462] Start a new discussion in jBPM Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
