Fixed version (ground truth):

      @SuppressWarnings("String_Node_Str") final DimensionField[] dims=index.getIndexModel().getDimensions();
      boolean hasLat=false;
      boolean hasLong=false;
      boolean hasTime=false;
      for (      final DimensionField<?> dim : dims) {
        hasLat|=dim instanceof LatitudeField;
        hasLong|=dim instanceof LongitudeField;
        hasTime|=dim instanceof TimeField;
      }
      if (hasLat && hasLong) {
