>    Affects Versions: 3.5.0-Beta-3
>            Reporter: Scott Marlow
>            Assignee: Scott Marlow
>             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).
