Attempt to bulk-delete Employee records without nulling foreign key references from InsurancePlan
-------------------------------------------------------------------------------------------------

                 Key: JDO-411
                 URL: http://issues.apache.org/jira/browse/JDO-411
             Project: JDO
          Issue Type: Bug
          Components: tck20
    Affects Versions: JDO 2 final
            Reporter: Marc Prud'hommeaux


Multiple test cases attempt to bulk delete instances of Person. However, the Employee subclass
of Person might wind up having a non-nullable foreign key reference to Insurance or another
Employee (via the "mentor" field). While the defaut Derby TCK schema does not have this constraint,
in order to be flexible for other databases that will enforce the foreign key by default,
some effort should be made to ensure that there are no relation constraints before the bulk
deletes are attempted. This can be done by adding a nullForeignKeyReferences() method that
will manually make sure that the relations are nulled. See the attached patch.

This affects the following tests:

 org.apache.jdo.tck.query.delete.DeletePersistentAll.testNoParametersAPI
 org.apache.jdo.tck.query.delete.DeletePersistentAll.testNoParametersSingleString
 org.apache.jdo.tck.query.delete.DeletePersistentAll.testObjectArrayParametersAPI
 org.apache.jdo.tck.query.delete.DeletePersistentAll.testObjectArrayParametersSingleString
 org.apache.jdo.tck.query.delete.DeletePersistentAll.testMapParametersAPI
 org.apache.jdo.tck.query.delete.DeletePersistentAll.testMapParametersSingleString
 org.apache.jdo.tck.query.delete.DeleteQueryElements.testAPI
 org.apache.jdo.tck.query.delete.DeleteQueryElements.testSingleString
