Kevin,
I think there is a problem in OpenJPA when you have the @Version annotation
on a class and it is a java.sql.Timestamp object. When you have this
situation, OpenJPA gives you the exception I listed below.
I know that Hibernate recommends against this, but it is a part of the JPA
spec to allow for Timestamp columns to act as @Version objects.
