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

[sumatheja]

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.
