Hi

I've managed to successfully use JBPM v5 persistence with MySQL a while back. I recently removed all the MySQL jbpm tables because I wanted clean the DB, now I am getting problems with creating new JBPM tables in the DB. I've spent a whole day looking for reference about this problem and most of the example persistence.xml and orm.xml files matches what I have. Is there suppose to be a proper way to create the MySQL tables ?

This is the error I am getting

Hibernate: insert into SessionInfo (lastModificationDate, rulesByteArray, startDate, OPTLOCK) values (?, ?, ?, ?)
