If you change the border of a JToggleButton from the default
border to a line border using BorderFactory.createLineBorder(Color.black)
then the hilighting no longer works when the button is selected in
a button group.

Using the code for SimpleExample as a base I changed the JButton to a JToggleButton
and changed the border. I've reproduced this in my own code as well. If seems
only to occurr in the Windows L&F.

public class SimpleExample extends JPanel {
    static JFrame frame;

    static String metal= "Metal";
    static String metalClassName = "com.sun.java.swing.plaf.metal.MetalLookAndFeel";

    static String motif = "Motif";
    static String motifClassName =
"com.sun.java.swing.plaf.motif.MotifLookAndFeel";

    static String windows = "Windows";
    static String windowsClassName =
"com.sun.java.swing.plaf.windows.WindowsLookAndFeel";

    JRadioButton metalButton, motifButton, windowsButton;

    public SimpleExample() {
// Create the buttons.
JToggleButton button = new JToggleButton("Hello, world");
        button.setMnemonic('h'); //for looks only; button does nada
        button.setBorder(BorderFactory.createLineBorder(Color.black));

metalButton = new JRadioButton(metal);
        metalButton.setMnemonic('o');
metalButton.setActionCommand(metalClassName);

motifButton = new JRadioButton(motif);
        motifButton.setMnemonic('m');
motifButton.setActionCommand(motifClassName);

windowsButton = new JRadioButton(windows);
        windowsButton.setMnemonic('w');
windowsButton.setActionCommand(windowsClassName);

// Group the radio buttons.
ButtonGroup group = new ButtonGroup();
group.add(metalButton);
group.add(motifButton);
group.add(windowsButton);

        // Register a listener for the radio buttons.
RadioListener myListener = new RadioListener();
metalButton.addActionListener(myListener);
motifButton.addActionListener(myListener);
windowsButton.addActionListener(myListener);

add(button);
add(metalButton);
add(motifButton);
add(windowsButton);
    }


    /** An ActionListener that listens to the radio buttons. */
    class RadioListener implements ActionListener {
public void actionPerformed(ActionEvent e) {
String lnfName = e.getActionCommand();

            try {
UIManager.setLookAndFeel(lnfName);
SwingUtilities.updateComponentTreeUI(frame);
frame.pack();
            }
catch (Exception exc) {
JRadioButton button = (JRadioButton)e.getSource();
button.setEnabled(false);
updateState();
                System.err.println("Could not load LookAndFeel: " + lnfName);
            }

}
    }

    public void updateState() {
String lnfName = UIManager.getLookAndFeel().getClass().getName();
if (lnfName.indexOf(metal) >= 0) {
metalButton.setSelected(true);
} else if (lnfName.indexOf(windows) >= 0) {
windowsButton.setSelected(true);
} else if (lnfName.indexOf(motif) >= 0) {
motifButton.setSelected(true);
} else {
System.err.println("SimpleExample if using an unknown L&F: " + lnfName);
}
    }

    public static void main(String s[]) {
/*
NOTE: By default, the look and feel will be set to the
Cross Platform Look and Feel (which is currently Metal).
The user may someday be able to override the default
via a system property. If you as the developer want to
be sure that a particular L&F is set, you can do so
by calling UIManager.setLookAndFeel(). For example, the
first code snippet below forcibly sets the UI to be the
System Look and Feel. The second code snippet forcibly
sets the look and feel to the Cross Platform L&F.

Snippet 1:
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (Exception exc) {
System.err.println("Error loading L&F: " + exc);
}

Snippet 2:
try {
UIManager.setLookAndFeel(UIManager.getCrossPlatformLookAndFeelClassName());
} catch (Exception exc) {
System.err.println("Error loading L&F: " + exc);
              }
*/

SimpleExample panel = new SimpleExample();

frame = new JFrame("SimpleExample");
frame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {System.exit(0);}
});
frame.getContentPane().add("Center", panel);
frame.pack();
frame.setVisible(true);

panel.updateState();
    }
}
