I'm looking at some code here in 5.4.0 (jbpm-flow/5.4.0.Final/jbpm-flow-5.4.0.Final-sources.jar):
org.jbpm.marshalling.impl.AbstractProtobufProcessInstanceMarshaller.readProcessInstance(MarshallerReaderContext)
it goes like this on line 373:
Process process = ruleBase.getProcess( processId );
if ( ruleBase != null ) {
processInstance.setProcess( process );
}
Isn't this code incorrect? If rule base were to be null it would have failed on the first line itself.
May be the code should be:
if ( process != null ) {
processInstance.setProcess( process );
}
Not sure.
I guess I'm running into this issue when i try to load the process instance:
ProcessInstance pid = ksession.getProcessInstance(16);
java.lang.NullPointerException
