[rules-users] "java.lang.AbstractMethodError: org.jbpm.marshalling.impl.ProcessMarshallerImpl.init" while unmarshalling statefulknowledgesession

[sumatheja]

I'm getting the same issue when I try to unmarshall a sample application
which has the jbpm process (which moves out guvnor as possible cause).....
can someone guide if this is some bug? or should I change the jbpm jar
version?
