--------------------------------------------------------------
Hello Everyone,
I am getting an exception when configuring jbpm 5.1 on jboss 5.1 with mysql 5.1.
I have modified hibernate.cfg.xml, persistence.xml, testDS1.xml, jbpm-human-task-5.1.0.Final.jar and I am able to export the jbpm schema in my sql tables.
4 new tables : eventtypes, processinstanceinfo,sessioninfo, workiteminfo got created into the database named jbpm_demo within mysql.
However when i try to open the console i get the above exception.

I think the exception is comming due to modifications required in jbpm-human-task-5.1.0.Final.jar . Did anyone face the similar exception (Exception stack trace @ bottom)

Here is the information from the modified files @ the time of exception:

jbpm-human-task-5.1.0.Final.jar: persistence.xml :
