#38840 — Graphics2D#fill3DRect?

I don't see any 3D effect.  Running on Windows 8 with OpenJDK 11.0.2. 
Screen capture of window at http://knutejohnson.com/test.png.  I tried 
it with the Graphics#fill3DRect too and got the same results.  Anybody 
see anything different?

Thanks!

import java.awt.*;

import javax.swing.*;

public class test extends JPanel {
     public test() {
         setPreferredSize(new Dimension(640,480));
     }

     public void paintComponent(Graphics g2D) {
         Graphics2D g = (Graphics2D)g2D;

         Rectangle b = getBounds(null);

         g.setColor(Color.WHITE);
         g.fill(b);

         g.setColor(Color.BLUE);
         g.fill3DRect(b.x+40,b.y+40,b.width-80,b.height-80,true);
     }

     public static void main(String... args) {
         EventQueue.invokeLater(() -> {
             JFrame f = new JFrame("test");
             f.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
             f.add(new test(),BorderLayout.CENTER);
             f.pack();
             f.setVisible(true);
         });
     }
}

If I switch to gray for the background and white for the rectangle I now 
see 1 pixel of edge on the right and bottom sides (I think).

Thanks!
