 * This test was added for https://issues.apache.org/jira/browse/OPENJPA-1892.
 *
 * The key to this test is that the ChildUncacheable is uncacheable and ParentUnspecifiedEntity is cacheable. In the
 * case were we pass the root Entity in em.find(ParentUnspecifiedEntity.class, 1) AND the id we passed corresponds to
 * the child Entity we shouldn't be caching this result.
