[jira] Created: (OPENJPA-939) Allow query on subclass field on superclass extent under specific hint

Allow query on subclass field on superclass extent under specific hint
----------------------------------------------------------------------

                 Key: OPENJPA-939
                 URL: https://issues.apache.org/jira/browse/OPENJPA-939
             Project: OpenJPA
          Issue Type: Improvement
            Reporter: Pinaki Poddar


According to user [1], OpenJPA throws parse exception if JPQL on a superclass uses subclass field in path expressions.
And, of course, the user reminds us that 'Hibernate can do it'. 
Given that it is not a kosher thing to do always, we should allow it only user sets subclass hints to true.
