getTasksAssignedAsPotentialOwner empty with RemoteJmsRuntimeEngineFactory

[guyr]

Following the examples in the Chapter 17 of the documentation, I started out with RemoteRestRuntimeFactory.  I got that working well: getTasksAssignedAsPotentialOwner() returned the correct set of tasks, and I was able to claim, start and complete tasks.  However, our code uses Jersey to provide REST services to other applications.  I discovered when I tried to deploy our code using RemoteRestRuntimeFactory that it does not work.  RestEasy and Jersey cannot co-exist; the app gets this runtime error:

java.lang.ClassCastException: com.sun.jersey.server.impl.provider.RuntimeDelegateImpl cannot be cast to org.jboss.resteasy.spi.ResteasyProviderFactory

So, I tried switching to RemoteJmsRuntimeEngineFactory.  This is more difficult to configure than RemoteRestRuntimeFactory.  You need to run add-user.bat in JBoss 7 to the ApplicationRealm for the userName you use to establish the JMS connection.  Then you need to update standalone-full.xml to add each role you are querying to security-settings.  So, now the test app is working with JMS, but taskService.getTasksAssignedAsPotentialOwner is returning no tasks.  I'm not seeing any errors in the JBoss log.  I know I'm connecting because getTaskService().getTasksByProcessInstanceId(1) *does* work.  But we really need getTasksAssignedAsPotentialOwner.

Any ideas?  I searched this forum looking for JMS and found very few posts.  Has anyone actually used the RemoteJmsRuntimeEngineFactory successfully?

Here is the codeI use to toggle between REST and JMS:

	if (fRest)
	{
	RemoteRestRuntimeFactory restRuntimeFactory = new RemoteRestRuntimeFactory(JBPM_DEPLOYMENT_ID, JBPM_BASE_URL, JBPM_USER, JBPM_PASSWORD);

	engine = restRuntimeFactory.newRuntimeEngine();
	}
	else
	{
	java.util.Hashtable<String, String> env = new java.util.Hashtable<String, String>();

	env.put(InitialContext.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
	env.put(InitialContext.PROVIDER_URL, "remote://localhost:4447");
	// env.put( InitialContext.URL_PKG_PREFIXES, "org.jboss.naming" );
	env.put(InitialContext.SECURITY_PRINCIPAL, "salaboy"); // salaboy
	env.put(InitialContext.SECURITY_CREDENTIALS, "salaboypw");

	InitialContext remoteInitialContext = null;
	try
	{
	remoteInitialContext = new InitialContext(env);
	}
	catch (NamingException e)
	{
	e.printStackTrace();
	}

RemoteJmsRuntimeEngineFactory jmsRuntimeFactory = new RemoteJmsRuntimeEngineFactory(JBPM_DEPLOYMENT_ID, remoteInitialContext, JBPM_USER, JBPM_PASSWORD);

engine = jmsRuntimeFactory.newRuntimeEngine();

}

KieSession ksession = engine.getKieSession();

TaskService taskService = engine.getTaskService();

AuditLogService auditLogService = engine.getAuditLogService();
