> Whenever the ChangeManager restores a RowKeySet, it changes the identity of the underlying object.  This surprises application developers who may have held onto the original instance in order to mutate it and results in the wrong objects being used by the application in many cases.  The solution is to preserve the object identity in all cases by reusing the existing RowKeySet and simply clearing it and then adding the new values.
