regression, we are no longer throwing  PessimisticLockException as required by the JPA-2 spec
---------------------------------------------------------------------------------------------

                 Key: HHH-4850
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4850
             Project: Hibernate Core
          Issue Type: Bug
    Affects Versions: 3.5.0-Beta-3
            Reporter: Scott Marlow
            Assignee: Scott Marlow
            Priority: Blocker
             Fix For: 3.5.0-Beta-4


It looks like the fix for HHH-4806 caused this to regress.

3.4.4.2 
"
When an application locks an entity with LockModeType.PESSIMISTIC_READ and later updates
that entity, the lock must be converted to an exclusive lock when the entity is flushed to the database[42].
If the lock conversion fails, and the database locking failure results in transaction-level rollback, the
provider must throw the PessimisticLockException and ensure that the JTA transaction or
EntityTransaction has been marked for rollback. When the lock conversion fails, and the database lock-
ing failure results in only statement-level rollback, the provider must throw the LockTimeoutEx-
ception (and must not mark the transaction for rollback).
