@Override
public Object clone() {      
  try {
    WeakSet<E> nws = (WeakSet<E>) super.clone();
    // sharing load factor is ok
    // but we can not share maps, recreate them
    nws.m = new SharedKeyWeakHashMap<E, Boolean>(size(), loadFactor);
    nws.s = nws.m.keySet();
    nws.addAll(this);
    return nws;
  } catch (CloneNotSupportedException e) {
    throw new IllegalStateException("base class doesn't support clone", e); // NOI18N
  }
}
