 * <B>Assertion Description: </B> If <code>PersistenceManager.getObjectById</code> is called with a
 * value of <code>true</code> for the second parameter named <code>validate</code>, and there is not
 * an instance already in the cache with the same JDO identity as the oid parameter, then this
 * method creates an instance with the specified JDO identity, verifies that it exists in the data
 * store, and returns it.
 *
 * <OL TYPE=A>
 *   <LI>If there is no transaction in progress, the returned instance will be hollow or
 *       persistent-nontransactional, at the choice of the implementation.
 *   <LI>If there is a data store transaction in progress, the returned instance will be
 *       persistent-clean.
 *   <LI>If there is an optimistic transaction in progress, the returned instance will be
 *       persistent-nontransactional.
