Buggy source:

Fixed version (ground truth):

  if (!frames.isEmpty())   throw new RuntimeException("String_Node_Str");
  Map<String,View> remainingViews=new LinkedHashMap<>();
  for (  View v : views)   remainingViews.put(v.viewId,v);
  if (groupArr != null) {
    for (    FrameArrangement frameArr : reversed(groupArr.frameArrs)) {
      MultiSplitPane.Node dockerRoot=toDockingPaneNode(frameArr.dockerArr,remainingViews,tileFactory);
      if (dockerRoot != null) {
        DockingFrame frame=addNewFrame();
        frame.setBounds(frameArr.x,frameArr.y,frameArr.width,frameArr.height);
        frame.setNormalBounds(frameArr.x,frameArr.y,frameArr.width,frameArr.height);
        frame.setExtendedState(getFrameExtendedState(frameArr));
        frame.setVisible(true);
        frame.docker.restore(dockerRoot);
      }
    }
  }
  if (!remainingViews.isEmpty()) {
    DockingFrame frame;
    if (frames.isEmpty()) {
      Tile tile=tileFactory.newTile();
      appendViewsToTile(tile,remainingViews.values());
      frame=addNewFrame();
      frame.docker.addInitialLeaf(tile);
      frame.setLocationByPlatform(true);
      frame.setSize(1024,768);
      frame.setVisible(true);
    }
