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

[Michael Anstis]

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.
