JavaFX et Swing redimensionnable JFXPanel

Question

Je veux un webview redimensionnable dans InternalFrame mais ce que j'ai des plantages. Ceci est mon code:

/** 
* Create the frame. 
*/ 
public TestBtn() { 
    setClosable(true); 
    setResizable(true); 
    setMaximizable(true); 
    setIconifiable(true); 
    getContentPane().setBackground(Color.GRAY); 

    JFXPanel panel = new JFXPanel(); 
    getContentPane().add(panel, BorderLayout.CENTER); 
    getContentPane().add(panel, BorderLayout.CENTER); 
    setBounds(100, 100, 764, 546);  
    Platform.runLater(new Runnable() { 
     @Override 
     public void run() { 
      initFX(panel); 
     } 
    }); 
    this.addComponentListener(new ComponentAdapter() { 
     @Override 
     public void componentResized(ComponentEvent e) { 
      initFX(panel); 
     } 
    }); 
} 
private static void initFX(JFXPanel fxPanel) { 
    // This method is invoked on the JavaFX thread 
    Scene scene = createScene(); 
    fxPanel.setScene(scene); 

} 

private static Scene createScene() { 
    Group root = new Group(); 
    Scene scene = new Scene(root); 
    WebView view = new WebView(); 
    WebEngine engine = view.getEngine(); 
    engine.onResizedProperty(); 
    engine.load("http://google.bg"); 
    root.getChildren().add(view); 

    return (scene); 
} 

public static void main(String[] args) { 
    SwingUtilities.invokeLater(new Runnable() { 
     public void run() { 
      try { 
       TestBtn frame = new TestBtn(); 
       frame.setVisible(true); 
      } catch (Exception e) { 
       e.printStackTrace(); 
      } 
     } 
    }); 
} 

Je reçois cette erreur après que j'essaie de maximiser la fenêtre InternalFrame:

Vous essayez de modifier les composants JavaFX sur le fil Swing. Je pense que c'est dans votre écouteur de composant. Essaye ça.

panel.addComponentListener(new ComponentAdapter() { 
    @Override 
    public void componentResized(ComponentEvent e) { 
     Platform.runLater(new Runnable() { 
      @Override 
      public void run() { 
       initFX(panel); 
      } 
     }); 
    } 
});
