I tried to adapt the the +WSHumanTaskHandler+ to a +LocalHumanTaskHandler+. But when
executing +taskSession.taskOperation(Operation.Complete, task.getId(), "krisv",
null, null, null),+ it throws following exception:
java.lang.NullPointerException

Attached you can find my LocalHumanTaskHandler.java and PersistentProcessExample.java
(main).
FYI, when I use instead of a +JPAKnowledgeService.newStatefulKnowledgeSession( kbase,
null, env )+ a +kbase.newStatefulKnowledgeSession()+ (non-JPA), it works fine.
