Cannot change JToggleButton background color when Windows XP theme is used

Question

I wanted to change the background of a JToggleButton when it's pressed. I tried a few things, such as
UIManager.put("ToggleButton.select", Color.RED);
setting button's background, button's UI.
but nothing worked.
so I tried changing desktop theme from Windows XP to Windows Classic, then i was able to set button's background.
The following is a simple test program, by switching theme, the toggleButton looks differently.
Does anyone know how I can change JToggle button's background color under Windows XP theme?
Thank you in advance!
import javax.swing.*;
import java.awt.*;
public class ToggleTest {
    public static void createGUI(){
        JToggleButton button = new JToggleButton("Test");
        button.setBackground(Color.BLUE);
        JFrame testFrame = new JFrame("Test Frame");
        testFrame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
        testFrame.getContentPane().setLayout(new FlowLayout(FlowLayout.CENTER));
        testFrame.getContentPane().add(button);
        testFrame.pack();
        testFrame.setVisible(true);
    public static void main(String[] args){
        try{
            UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
            //UIManager.put("ToggleButton.select", Color.RED);
        catch(Exception ex){
            ex.printStackTrace();
        SwingUtilities.invokeLater(new Runnable(){
            public void run(){
                createGUI();
}

class myToggleBtn extends JToggleButton {
  String s;
  public myToggleBtn(String str, Boolean sel) {
    super(str, sel);
    s = str;
  public void paintComponent(Graphics g) {
    super.paintComponent(g);
    if (this.isSelected()) {
         int w = getWidth();
         int h = getHeight();
         g.setColor(Color.green); //selected color
         g.fillRect(0, 0, w, h);
         g.setColor(Color.darkGray); //selected foreground color
         g.drawString(s, (w - g.getFontMetrics().stringWidth(s))/2 + 1, (h + g.getFontMetrics().getAscent())/2 - 1);
}
