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.
