Hi,

I make a change to a POJO, but do not commit the change. I spawn a thread, (that uses it's own EntityManager) and which makes changes to the same POJO which it successfully commits. I then try to commit a the change in the original thread. I expect an javax.persistence.OptimisticLockException, but I get a javax.persistence.RolllbackException,

Why does Hibernate not chuck the OptimisticLockException?

Here are more details from the stack trace,

Hibernate now wrap the Stale exception into an OptimisticLockException

But remember that commit() has to wrap exceptions

@throws RollbackException if the commit fails.

so Optimistic lock exception will be wrapped ino a Rollbackexception
