> OmDBSnapshotInfoCodec.copyObject(..) is a shallow copy -- it simply returns the same object.  However, if it is changed to return a deep copy as shown in the second comment, TestOMSnapshotDeleteRequest and TestOMSnapshotPurgeRequestAndResponse will fail.  These two tests depend on the behavior that, after copying, changing one copy will also change the other copy.
