PessimisticLockException should be thrown when pessimistic read and write locking strategies fail
-------------------------------------------------------------------------------------------------

                 Key: HHH-6865
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6865
             Project: Hibernate Core
          Issue Type: Bug
          Components: core
    Affects Versions: 4.0.0.CR6
            Reporter: Gail Badner
            Assignee: Gail Badner
             Fix For: 4.0.0.next


In some cases, when a pessimistic read/write locking strategy fails with SQLException, Hibernate converts the SQLException to a org.hibernate.JDBCException, but does not wrap the JDBCException in a org.hibernate.PessimisticLockException.

This affects:
PessimisticReadSelectLockingStrategy.lock(...)
PessimisticReadUpdateLockingStrategy.lock(...)
PessimisticWriteSelectLockingStrategy.lock(...)
PessimisticWriteUpdateLockingStrategy.lock(...)

These methods specifically catch SQLException, convert it to a org.hibernate.JDBCException, and wrap in a org.hibernate.PessimisticLockException.

If Hibernate does the conversion immediately when the statement fails and throws JDBCException, then lock(...) does not have the opportunity to catch it and wrap it in a org.hibernate.PessimisticLockException.

This issue is reproduced in LockTest failures on Oracle.
