Parentheses dissapear in simple JPQL update query where they should stay
------------------------------------------------------------------------

                 Key: HHH-6714
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6714
             Project: Hibernate Core
          Issue Type: Bug
          Components: entity-manager
    Affects Versions: 4.0.0.CR4, 3.6.7
         Environment: Tried on Hibernate 3.6.7 and 4.0.0.CR4 with PostgreSQL database
            Reporter: Peter Gwiazda


I create simple update query
{noformat}       
em.createQuery("update WorkMessage workMessage set workMessage.earnedPrice = -( workMessage.totalCost - :a1 )")
                .setParameter("a1", 12.0f)
                .executeUpdate();
{noformat}

and the SQL is (yelled by hibernate log)

{noformat}
09:18:10.880 [main] DEBUG org.hibernate.SQL - update work_message set earned_price=-total_cost-?
{noformat}

{{- total_cost - 12}} is not the same as {{- (total_cost - 12)}}
