Description Marek Baluch 2013-08-20 17:23:59 UTC

Description of problem:
The following code will throw the stack trace in 'Stack-Trace:' section. Initialization of the RemoteRuntimeEngineFactory was made to create a JMS client.

RemoteRuntimeEngineFactory factory = new RemoteJmsRuntimeEngineFactory(/* ... */);
RuntimeEngine runtimeEngine = factory.newRuntimeEngine();
KieSession kieSession = runtimeEngine.getKieSession();
kieSession.startProcess("processId", null);


Stack-Trace:
java.lang.NullPointerException

Comment 1 Marco Rietveld 2013-09-04 10:40:07 UTC

This was fixed along the way by a number of small commits. 

This method here: 

https://github.com/droolsjbpm/droolsjbpm-integration/blob/6.0.x/kie-remote/kie-services-remote/src/main/java/org/kie/services/remote/jms/RequestMessageBean.java#L253

now makes sure that the NPE doesn't happen.
