I'm trying to deploy jbpm 5.2 on jboss 7.0.2 and keep running into the following problem :

Caused by: org.hibernate.MappingException: *Could not determine type for: java.util.Set, at table: ProcessInstanceInfo, for columns: [org.hibernate.mapping.Column(eventTypes)]*

When I configured my personal persistence.xml and orm.xml, I referenced  https://community.jboss.org/message/643956#643956 https://community.jboss.org/message/643956, which is really a similiar problem. This fixed by initial startup (as I changed my old ProcessInstancesWaitingForEvent query to the suggested one at the bottom of the conversation). Now, however, when Spring is deploying, I'm seeing the same issue :

I made sure ALL references to any orm.xml had this new query. When I searched against the jbpm 5.2 jars, I found that *jbpm-persistence-jpa-5.2.0.Final.jar* had its own orm.xml and JBPMorm.xml that was using the "old" query (and version=1.0). I manually changed these to use the "new" query and redeployed, but with no luck. Is this a Hibernate 4 issue? A JPA mismatch issue? Am I possible configuring Spring incorrectly? 

ANY information would be helpful. 

(Using a mysql DB with MySQL connector jar, by the way)
