Graphics draw and fill methods work incorrectly with AlphaComposite different from AlphaComposite.Src

Simple reproducer:
import java.io.*; 
import java.awt.*; 
import java.awt.image.*; 
import javax.swing.*; 

public class FillRectTest extends JFrame { 
   public static void main(String[] args){ 
      final FillRectTest test = new FillRectTest(); 
      test.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
      test.setSize(200, 200); 
      test.add(new Panel(){
          public void paint(Graphics g){
              Composite composite = AlphaComposite.Clear;
              int w = getWidth();
              int h = getHeight();

              g.setColor(Color.green);
              g.fillRect(0, 0, w, h);
              Graphics2D g2d = (Graphics2D)g;
              g2d.setColor(Color.red);
              g2d.setComposite(composite);
              g2d.fillRect(w/4, h/4, w/2, h/2);
          }
      });
      test.setVisible(true);
   } 
}
