I have got the different result on Mac

I just want to share two results I have got on My Mac. I transcribed all of this article. Creating Visual Effects in JavaFX: About This Document | JavaFX 2 Tutorials and Documentation Also the article is written by @skrb using InvalidationListener.
The result that I saw was different from what I had expected. The one is blend mode and another is InvalidationListener.

• The environment is Mac OS X 10.7.4 with JDK7

• Figure 1(Blend Mode)

• Code 1

This code shows using 3 type of blend mode. But Figure 1 shows the same result...
It seems like BlendMode.SRC_ATOP does not work on Mac?
(see Creating Visual Effects in JavaFX: Blending Objects | JavaFX 2 Tutorials and Documentation)

public class BlendSample extends Application {
    @Override
    public void start(Stage stage) throws Exception {
        HBox root = new HBox();
        root.setPadding(new Insets(10));
        root.setSpacing(8);
        // Blending
        Node node1 = getBlendMode(BlendMode.MULTIPLY, Color.BLUE);
        Node node2 = getBlendMode(BlendMode.SRC_ATOP, Color.ORANGE); // This has the different result
        Node node3 = getBlendMode(BlendMode.SRC_OVER, Color.AQUA);
        root.getChildren().addAll(node1, node2, node3);
        stage.setScene(new Scene(root, 500, 300));
        stage.show();
    }

    static Node getBlendMode(BlendMode mode, Color color) {
        Rectangle r = new Rectangle();
        r.setX(590);
        r.setY(50);
        r.setWidth(50);
        r.setHeight(50);
        r.setFill(color);

        Circle c = new Circle();
        c.setFill(Color.rgb(255, 0, 0, 0.5f));
        c.setCenterX(590);
        c.setCenterY(50);
        c.setRadius(25);

        Group g = new Group();
        g.setBlendMode(mode);
        g.getChildren().add(r);
        g.getChildren().add(c);
        return g;
    }

• Figure 2(InvalidationListener)

InvalidationListener called only once but it should be twice.

• Code 2

package javaapplication22;

import javafx.beans.InvalidationListener;
import javafx.beans.Observable;
import javafx.beans.property.SimpleIntegerProperty;

public class BindDemo {
    public static void main(String[] args) {
        SimpleIntegerProperty x = new SimpleIntegerProperty(0);
        SimpleIntegerProperty y = new SimpleIntegerProperty();
        y.bind(x);
        y.addListener(new InvalidationListener() {
            @Override
            public void invalidated(Observable o) {
                System.out.println("Invalidate:" + o);
            }
        });
        System.out.println(y.get());  // This code works without invalidationListener?
        x.set(10);
        x.set(20);
        System.out.println(y.get());
    }
}

When I run any JavaFX programs and maximize the screen then quit the application, the error message as follows appears on NetBeans.

I would appreciate any advice since I am very beginner of JavaFX.
keep coding....
