You are removing an element from the backing store of the iterator. The
iterator that you get from ArrayList is fail-fast. Which means that it
tries to detect any changes occurring to the backing store and throws an
exception if that happens and it is detected. JCL2ev1sup says that
nextIndex can throw a ConcurrentModificationException if the list was
modified by something else than this list iterator and that is precisely
what happens here.
