Ensure comparisons do not contain two parameters with Derby (ie SELECT ... WHERE ? = ?)
---------------------------------------------------------------------------------------

                 Key: OPENJPA-1217
                 URL: https://issues.apache.org/jira/browse/OPENJPA-1217
             Project: OpenJPA
          Issue Type: Bug
          Components: jdbc
         Environment: Derby Embedded
            Reporter: Michael Dick


The problem appears to be Derby specific and can be seen by running o.a.o.p.c.TestTypesafeCriteria.testTrue()
and testFalse(). 

It's not related to criteria - the problem exists in the JPQL query. I believe I've seen this
issue before but couldn't find it in JIRA. The relevant stack traces follow:
