I am using the JBM5 5.2.0-SNAPSHOT with Hibernate 3.6.0.Final. My pom is pretty standard with required dependencies (jbpm-human-task,
jbpm-persistence-jpa, etc) 


My persistence.xml and orm.xml resemble - 
 https://github.com/Salaboy/emergency-service-drools-app/tree/master/emergency-service-core/src/main/resources/META-INF/orm.xml https://github.com/Salaboy/emergency-service-drools-app/tree/master/emergency-service-core/src/main/resources/META-INF/orm.xml

Starting the HumanTaskService however is throwing exceptions for the TaskSummary. Is anyone else facing similar problems ?
