    Clone is broken, so dont use it.

    THE CLONE METHOD of the Object class
    is a somewhat magical method that does
    what no pure Java method could ever
    do: It produces an identical copy of
    its object. It has been present in the
    primordial Object superclass since the
    Beta-release days of the Java
    compiler*; and it, like all ancient
    magic, requires the appropriate
    incantation to prevent the spell from
    unexpectedly backfiring

    Prefer a method that copies the object

    Foo copyFoo (Foo foo){
  Foo f = new Foo();
  //for all properties in FOo
  f.set(foo.get());
  return f;
}
