---------------------------------------

Hum, quite funny indeed...
I'm trying to reverse engineer the spring jpetstore database and I run into the same kind of problem.
In this case, the problem is a DATE column named TIMESTAMP. HibernateTool generates a version element with a date type but as org.hibernate.type.DateType doesn't implement org.hibernate.type.VersionType, I get a ClassCastException.
