Buggy source:
private void loadObjects(final int page,final boolean shouldClear){
  final ParseQuery<T> query=this.queryFactory.create();
  if (this.objectsPerPage > 0 && this.paginationEnabled) {
    this.setPageOnQuery(page,query);
  }
  this.notifyOnLoadingListeners();
  if (page >= objectPages.size()) {
    objectPages.add(page,new ArrayList<T>());
  }
  final Capture<Boolean> firstCallBack=new Capture<>(true);
  query.findInBackground(new FindCallback<T>(){
    @SuppressLint("String_Node_Str") @Override public void done(    List<T> foundObjects,    ParseException e){
      if ((!Parse.isLocalDatastoreEnabled() && query.getCachePolicy() == CachePolicy.CACHE_ONLY) && (e != null) && e.getCode() == ParseException.CACHE_MISS) {
        return;
      }
      if ((e != null) && ((e.getCode() == ParseException.CONNECTION_FAILED) || (e.getCode() != ParseException.CACHE_MISS))) {
        hasNextPage=true;
      }
 else       if (foundObjects != null) {

Fixed version (ground truth):

  this.notifyOnLoadingListeners();
  if (page >= objectPages.size()) {
    objectPages.add(page,new ArrayList<T>());
  }
  final Capture<Boolean> firstCallBack=new Capture<>(true);
  runningQueries.add(query);
  query.findInBackground(new FindCallback<T>(){
    @Override public void done(    List<T> foundObjects,    ParseException e){
      if (!runningQueries.contains(query)) {
        return;
      }
      if (query.getCachePolicy() != CachePolicy.CACHE_THEN_NETWORK || (query.getCachePolicy() == CachePolicy.CACHE_THEN_NETWORK && !firstCallBack.get())) {
        runningQueries.remove(query);
      }
      if ((!Parse.isLocalDatastoreEnabled() && query.getCachePolicy() == CachePolicy.CACHE_ONLY) && (e != null) && e.getCode() == ParseException.CACHE_MISS) {

      }

        hasNextPage=true;
