> 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.
