Until both projects have their releases out, you will have to use snapshots. jBPM 5.3 requires Drools 5.4 and vice-versa. You can't use Drools 5.4 with jBPM 5.2.<div>

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.<div>

<p>There was a dramatic change to the marshalling of binary packages for 5.4.CR1. AFAIK this would mean any existing binary package in Guvnor would need to be rebuilt. </p>
<p>Downgrading JARs to older versions would effectively remove the marshalling change and hence restore compatibility of older binary assets.</p>
<p>Edson, I think I am right? We need to call this loud and clear in the release notes.</p>

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?<br>

Hi,<br> I'm using drools and guvnor 5.4 cr1. I've few drools ruleflows which were not executing so I imported the jars from jbpm 5.2 final..... The marshalling and unmarshalling works fine if I have knowledge base without rule-flows. I hope this gives some hint..<div>

This kind of error indicates some confusion between compilation and<br>
execution of the code where this is thrown.<br>
<br>
Also, which versions of Drools do you used for marshalling and<br>
unmarshalling? There's no line 287 in the versions of<br>
org.drools.marshalling.impl.PersisterHelper.java available to me.<br>
