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

Hi Michael... Thanks for the response.... I'm getting this exception even without a guvnor i.e. when I use a local project which has jbpm process and a drl file.... but without the jbpm process everything works fine. I'm using jbpm 5.2 final. 2012/4/16 Michael Anstis <michael.anstis(a)gmail.com&gt; > There was a dramatic change to the marshalling of binary packages for > 5.4.CR1.
