      import javafx.scene.Scene;
      import javafx.scene.control.Label;
      import javafx.scene.layout.HBox;

      import javax.swing.JButton;
      import javax.swing.JFrame;
      import javax.swing.JLabel;
      import com.sun.javafx.application.PlatformImpl;

      import java.awt.FlowLayout;

      public class PreferredSize
      {

      Label l;
      JFXPanel fxPanel;
      HBox g;
      Scene scene;

          private PreferredSize()
          {
              final JFrame f = new JFrame("Test JFXPanel pref size");
              f.setSize(800, 600);
              f.setLocationRelativeTo(null);
              f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

              f.setLayout(new FlowLayout());
              f.add(new JButton("Button 1"));
              fxPanel = new JFXPanel();
              f.add(fxPanel);
              f.add(new JLabel("Label1"));

              PlatformImpl.startup(new Runnable()
              {
                  @Override
                  public void run()
                  {
                      g = new HBox();
                      l = new Label("bla");
                      g.getChildren().add(l);
                      scene = new Scene(g);

                      fxPanel.setScene(scene);
                      deblockThread();
                  }
              });
              
              blockThread();
              
              f.pack();
              f.setVisible(true);
          }
          
          public void setText(String text)
          {
           final String s = text;
           Platform.runLater(new Runnable(){

      @Override
      public void run() {
      l.setText(s);
      deblockThread();
      }
          
           });
           blockThread();
           System.out.println(g.getPrefWidth(0.0));
           System.out.println(g.getPrefHeight(0.0));
           System.out.println(g.getBoundsInParent());
          }

          private synchronized void blockThread()
      {
      try {
      this.wait();
      } catch (InterruptedException e1) {
      // TODO Auto-generated catch block
      e1.printStackTrace();
      }
      }

      private synchronized void deblockThread()
      {
      this.notify();
      }

          
          public static void main(String[] args)
          {
              PreferredSize p = new PreferredSize();
              p.setText("huhuhuhu");
          }
      }

      I start a JavaFX-Label in Swing and it gets autosized to the right size. Then i set a new Text with Platform.runLater();. Although the PrefSize-Methods of the label show the right values, the bounds of the label are not updated.
      I tried with adding the group to the dirtylayout list, i tried to revalidate it, i tried to repaint the jfxPanel, nothing updated the bounds of the label (control) / jfxPanel.
