I am using the LocalTaskService and here is the sequence of events that causes the problem.

1) My client starts a process then disposes the session.
2) My client loads the session that was disposed in step 1 and  claims the first task in the process.
3) My client loads the session that was disposed in step 1 and  starts the first task in the process.
*4) My client loads the session that was disposed in step 1 and  completes the first task in the process and JBPM throws the following exception:*

*Caused by: java.lang.IllegalStateException: Illegal method call. This session was previously disposed.
