'Iterator.next()' which can't throw 'NoSuchElementException'

Reports implementations of Iterator.next() that cannot throw java.util.NoSuchElementException.

Such implementations violate the contract of java.util.Iterator, and may result in subtle bugs if the iterator is used in a non-standard way.

Example:

class Numbers implements Iterator<Integer> {
  @Override
  public Integer next() { //warning
      if (hasNext()) {
          return generateNext();
      } else {
          return null; //throw NoSuchElementException instead
      }
  }

  ...
}
