Drop-shadow in an undecorated Pane

Question

I\'m trying to make my Pane a little bit better, visually, so, what I\'m doing is: set my stage UNDECORATED (OK) and (TRYING) to add a drop-shadow effect (NOT OK).

Stage dropshadow without FXML:

public void start(Stage stage){
    final double RADIUS = 5;
    VBox rootNode = new VBox();
    Insets bgInsets = new Insets(RADIUS);
    BackgroundFill bgFill = new BackgroundFill(Color.PINK, null, bgInsets);
    rootNode.setBackground(new Background(bgFill));
    DropShadow dropShadow = new DropShadow(RADIUS, Color.GRAY);
    rootNode.setEffect(dropShadow);

    Scene scene = new Scene(rootNode);
    scene.setFill(Color.TRANSPARENT);
    stage.setScene(scene);
    stage.initStyle(StageStyle.TRANSPARENT);
    stage.show();
}
