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()).
