Are you using JPAKnowledgeService to create your session? Are you calling the dispose method each time that you end up interacting with the session? Do you have the session loaded when you finish the human task?

See the code inside CommandBasedWSHumanTaskHandler.connect(). Remember (is not in official doc) that is not automatically the refresh of the session when you call taskClient.complete(...), you must explicity define a listener that must update the session state. You can extend CommandBasedWSHumanTaskHandler and make a setter of TaskClient or look this class to make your solution. I did a simple helper clasess to manage this.
