The error means a version incompatibility due to changes we made to the marshalling framework. 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.

   I think jBPM 5.3 has not released any binaries after Drools 5.4.CR1, so you need to use the snapshot until it is.

   Please note that this is temporary as we are talking about development (i.e., non-final) versions.

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.

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.

Downgrading JARs to older versions would effectively remove the marshalling change and hence restore compatibility of older binary assets.

Edson, I think I am right? We need to call this loud and clear in the release notes.

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?

Hi,
    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..

This kind of error indicates some confusion between compilation and
execution of the code where this is thrown.

Also, which versions of Drools do you used for marshalling and
unmarshalling? There's no line 287 in the versions of
org.drools.marshalling.impl.PersisterHelper.java available to me.
