@Override
public Map.Entry<String, Object> next() {
  Map.Entry<String, Object> entry = mapIterator.next();
  if (entry.getValue() instanceof Map) {
    return MapEntry.createUnmodifiable(entry.getKey(), new JsonObject((Map) entry.getValue()));
  }
  if (entry.getValue() instanceof List) {
    return MapEntry.createUnmodifiable(entry.getKey(), new JsonArray((List) entry.getValue()));
  }

    MapEntry<String, Integer> mapEntry1 = MapEntry.createUnmodifiable("foo", 3);

    try {
