title: Can't center nodes within a border pane
body: <p>I can't for the life of me figure out why I can't center a VBox within one of the sections within a border pane.</p>
  
  <pre><code>@Override
  public void start(Stage primaryStage) throws Exception{
      BorderPane root = new BorderPane();
      Scene scene = new Scene(root, 960, 600);
      primaryStage.setScene(scene);
      primaryStage.setTitle("Test application");
      primaryStage.setFullScreen(true);
      primaryStage.setFullScreenExitHint("Press escape to exit fullscreen");
      primaryStage.show();
      javafx.scene.image.Image icon = new Image("sample/Riverviewcrest.png");
      primaryStage.getIcons().add(icon);
  
      Pane paneleft = new Pane();
      Pane paneright = new Pane();
      Pane panecenter = new Pane();
      Pane panetop = new Pane();
      Pane panebottom = new Pane();
  
      paneleft.setPrefWidth(100);
      paneright.setPrefWidth(100);
      panetop.setPrefHeight(100);
      panebottom.setPrefHeight(100);
  
      panecenter.setStyle("-fx-background-color: #0053A8");
  
      root.setLeft(paneleft);
      root.setRight(paneright);
      root.setCenter(panecenter);
      root.setTop(panetop);
      root.setBottom(panebottom);
  
  
      Text test = new Text("Hello");
      Text test2 = new Text("Hello");
      Text test3 = new Text("Hello");
      Text test4 = new Text("Hello");
      VBox box = new VBox();
      box.getChildren().addAll(test, test2, test3, test4);
      panecenter.getChildren().add(box);
      root.setAlignment(box, Pos.CENTER);
  }
  
  public static void main(String[] args) {
      launch(args);
  }
  </code></pre>
  
  <p>The aim is to have the text centered within the center part of the border pane. Thanks for any and all help!</p>
