 * <B>Assertion Description: </B> 12.7.1 For retrieve with FGonly true, the implementation uses the
 * fetch plan to determine which fields are loaded from the datastore. With FGonly false, the
 * implementation reverts to JDO 1 behavior, which loads all fields from the datastore; in this
 * case, no related instances are loaded.
