>Description:
Object.clone() can throw the checked exception 
CloneNotSupportException. It is thus illegal to call clone()
without catching or throwing this exception. But gcj does
not detect this error.

class Clone
{
  Object a()
  {
    return super.clone();
  }
  
  Object b(Object obj)
  {
    return obj.clone();
  }
}
