New Revision: 802273

URL: http://svn.apache.org/viewvc?rev=802273&view=rev
Log:
OPENJPA-1013: 1. Avoid both LHS and RHS parameterized as ? = ? in SQL. Some databases do not
like it. 
                           2.  handle constant literal or empty arguments for Criteria predicates
.
                           3. Parameter registration for subqueries roll up to the parent
                           4. MapKey of kernel is not a path so allPathImpl.toValue() is not
kernel.Path

                            5. Clean up tests. Local result: Total : 435 Fails: 14 locally
