Hi

 

I am tryng to use WorkflowProcessInstanceUpgrader however when i invoke updateProcessInstance (..) passing a statefulknowledge session i get the following classcastexception:

 

org.drools.command.impl.CommandBasedStatefulKnowledgeSession cannot be cast to org.drools.common.InternalKnowledgeRuntime (line 61)

 

Has anyone seen this before?

 

Thanks
