Janela JFrame Recortado ou Transparente

Programação
#1

Bom dia!
Estava usando o com.sun.awt.AWTUtilities.setWindowShape(…); para Recortar o JFrame.
e
Estava usando o com.sun.awt.AWTUtilities.setWindowOpacity(…); para deixá-lo Transparente o JFrame.
Logo vi que esse código era ultrapassado.
Queria saber de um código atual para recortar o JFrame.
Alguém tem alguma ideia?

import java.awt.*;
import java.awt.geom.Ellipse2D;

import javax.swing.*;

public class ShapedWindow extends JFrame {
public ShapedWindow() {
super(“Test oval-shaped window”);
this.setLayout(new FlowLayout());
this.add(new JButton(“test”));
this.add(new JCheckBox(“test”));
this.add(new JRadioButton(“test”));
this.add(new JProgressBar(0, 100));

	this.setSize(new Dimension(400, 300));
	this.setLocationRelativeTo(null);
	this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}

public static void main(String[] args) {
	JFrame.setDefaultLookAndFeelDecorated(true);
	SwingUtilities.invokeLater(new Runnable() {
		@Override
		public void run() {
			Window w = new ShapedWindow();
			w.setVisible(true);
			com.sun.awt.AWTUtilities
					.setWindowShape(w, new Ellipse2D.Double(0, 0, w
							.getWidth(), w.getHeight()));
		}
	});
}

}

 setShape(new RoundRectangle2D.Double(
                x, //posição horizontal
                y, //posição vertical

                corner2)); //borda redonda 2

 setOpacity(0.8f); //float

Tem como fazer animação com o JFrame? Como?
