Sorry, I must have missed the email notification for the last comment. I'll create a test for you. Is there any standard practice for this? Branch off of Hibernate's repo, standalone repo, etc?

As far as the problem, even it you were to call ExceptionConverter#convert(RuntimeException, LockOptions), there's still nothing handling the case when the exception is a LockAcquistionException, and so it ends being wrapped in a PersistenceException and re-thrown.

I'll try to get to that test today case today
