21  * The NoOpObjectCopyStrategy does not make a copy. It merely returns the same object.
22  *
23  * For backwards compatability with OJB 0.9, we include a way to no-op copy
24  * the object into the transactional context. This means that we are operating
25  * on a live object, and can potentially mess stuff up. This is essentially
26  * supporting a uncommitted-read only strategy.
