I'm failing miserably at persisting a process with a timer.
I'm disposing the session before the timer expires. When I call JPAKnowledgeService.loadStatefulKnowledgeSession with the old session id I'm getting an exception. I've attached a test case with a simple maven project. Just use mvn test to see the issue.
Any help would be appreciated.
