   * <p>This bug is this: if you create an iterator from a TreeSet and call next() on that iterator
   * when hasNext() is false, so that next() throws a NoSuchElementException, then subsequent calls
   * to remove() will incorrectly throw an IllegalStateException, instead of removing the last
   * element returned.
