Hello,

I am starting a jbpm process using the following code:


                    KnowledgeBase kbase = readKnowledgeBase(); 
                    StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();


                    AsyncHornetQHTWorkItemHandler workItemHandler = new AsyncHornetQHTWorkItemHandler(ksession);

                    workItemHandler.setIpAddress("10.0.0.101");

                    ksession.getWorkItemManager().registerWorkItemHandler("Human Task", workItemHandler);

                    Map<String, Object> params = new HashMap<String, Object>();
                    params.put("employee", "krisv");

                    ksession.startProcess("defaultPackage.YesNo",params);


The first time through the process works fine.
Running the process again seems to log the results from the previous run through and throws an exception.

If I drop the jbpm5 schema and recreate it then it works fine again.
