[rules-users] Process instance status not completing when using JPA.

Hi, I'm seeing some odd behavior in Drools Flow 5.1.1. When using JPA and creating a StatefulKnowledgeSession using JPAKnowledgeService.newStatefulKnowledgeSession(), processes look like they run to completion, but calling RuleFlowProcessInstance.getState() on process instances created froim this knowledge session returns 1 (STATE_ACTIVE). Calling getActiveNodeIds() throws a NullPointerException. If I get a StatefulKnowledgeSession without JPA by calling KnowledgeBase.newStatefulKnowledgeSession(), getState() returns 2 (STATE_COMPLETED). I added KnowledgeRuntimeLoggerFactory.newConsoleLogger(knowledgeSession) and can see in both cases that the process is complete. Has this been seen before? Is it a known bug? Am I doing something wrong? Regards, Dan Nathanson
