SwingNode not useable on Raspberry PI

The following code needs Swing and doesn't run properly on a raspberry PI even if JavaFX support is enabled. 

/**
   * update the given tab with the given panel
   * 
   * @param tab
   * @param panel
   */
  public void updateTab(Tab tab, JPanel panel) {
    if (panel != null) {
      final SwingNode swingNode = new SwingNode();
      swingNode.setContent(panel);
      tab.setContent(swingNode);
    }
  }
