Buggy source:

Fixed version (ground truth):

    throw new JSONException("String_Node_Str");
  }
  Iterator<String> keys=jDaysObject.keys();
  String firstDayKey=keys.next();
  JSONObject firstDayObject=jDaysObject.getJSONObject(firstDayKey);
  this.otherViews=firstDayObject.getInt("String_Node_Str");
  this.totalViews=firstDayObject.getInt("String_Node_Str");
  JSONObject countryInfoJSON=response.optJSONObject("String_Node_Str");
  JSONArray viewsJSON=firstDayObject.optJSONArray("String_Node_Str");
  if (viewsJSON != null && countryInfoJSON != null) {
    countries=new ArrayList<>(viewsJSON.length());
    for (int i=0; i < viewsJSON.length(); i++) {
