Buggy source:

Fixed version (ground truth):

  }
 else {
    mWeek=EventHelper.weekNumFromLabel(mYear,mHeader);
  }
  events=new ArrayList<>();
  APIResponse<ArrayList<Event>> response;
  if (mYear != -1 && mWeek == -1 && mTeamKey == null) {
  }
 else   if (mYear != -1 && mWeek != -1 && mTeamKey == null) {
    try {
      response=DataManager.Events.getSimpleEventsInWeek(mFragment.getActivity(),mYear,mWeek,forceFromCache);
      if (isCancelled()) {
        return APIResponse.CODE.NODATA;
      }
      ArrayList<Event> eventData=response.getData();
      if (eventData != null && !eventData.isEmpty()) {
        events=EventHelper.renderEventListForWeek(eventData);
      }
