That produces some NPE at runtime, for instance in: at org.jbpm.workflow.instance.node.WorkItemNodeInstance.getWorkItem(WorkItemNodeInstance.java:65) when I execute: workItemNodeInstance.getWorkItem() All I do is:         StatefulKnowledgeSession session =         JPAKnowledgeService.                 newStatefulKnowledgeSession(knowledgeBase,                         getKnowledgeSessionConfiguration(),                             getEnvironment());         WorkflowProcessInstance processInstance = (WorkflowProcessInstance) session                 .startProcess(processId, params);         processInstance.getKnowledgeRuntime().toString() // NPE!!!!!!!!!!!!!! 2) The  ProcessInstance.getState() returns "STATE_ACTIVE" even when the process is (correctly) ended. All seems ok (the ProcessEventListener method are fired, etc)...but if I use the ProcessInstance getState() method to test the state, that returns always STATE_ACTIVE. I'm using JBPM 5.1 final.
