Consider the following code fragment:

		ArrayList<? super Integer> al = new ArrayList<Object>();
		al.add(new Integer(1)); // (1)
		Integer i = al.get(0);  // (2)

(1) gives you a compiler error. This is not correct because the list al contains 
elements of an unknown type, but the type must be a superclass of Integer
Therefore its completely legal to add an Integer

(2) compiles, but is not legal. The list can contain any type, so a cast to 
Integer is not save!
