Fair enough.  Keep it simple.

One can invoke clone only on types known to implement clone method (ArrayList, Set etc etc). Yes, if type implements Cloneable we could reasonably assume that it implemented clone method but still - we have to resort to reflection to invoke clone method but that route is even worse IMHO. I'd avoid this altogether.
