   * class are used instead of the regular ones obtained by
   * {@link Map#entrySet()}, then we need not worry about the actual field-names

   * Example: {@code ConcurrentHashMap.MapEntry} does not name the fields as key/
   * value in Java 1.8 while it used to do so in Java 1.7

   * @param <K> Key of the map-entry
   * @param <V> Value of the map-entry
