Bug in ArrayList iterator

[Remi Forax]

A simple Java question, what this code does ?

   ArrayList<String> list = new ArrayList<>();
   list.add("foo");
   list.add("bar");
   for(String s: list) {
     list.remove(s);
   }

:(

tip: the bug lies in ArrayList.Itr.hasNext() (and 
AbstractList.Itr.hasNext()).
