Buggy source:

      }
 else {
        renderEmptyViewText(gl,new String[]{"String_Node_Str","String_Node_Str","String_Node_Str"});
      }
      gl.glEndList();
      isDisplayListDirty=false;
    }
    gl.glCallList(displayListIndex);

Fixed version (ground truth):

      if (tourguide.hasTourGuide()) {
        renderEmptyViewText(gl,new String[]{"String_Node_Str","String_Node_Str","String_Node_Str","String_Node_Str","String_Node_Str"});
      }
 else {
        renderEmptyViewText(gl,new String[]{"String_Node_Str","String_Node_Str","String_Node_Str"});
      }
      gl.glEndList();
      isDisplayListDirty=false;
    }
    gl.glCallList(displayListIndex);
  }
 else {
    if (!uninitializedSubViews.isEmpty()) {
      while (uninitializedSubViews.peek() != null) {
        uninitializedSubViews.poll().initRemote(gl,this,glMouseListener);
