Suppose the following program: 
----- 
import javax.swing.*; 
import java.awt.*; 
 
class M extends JFrame{ 
    private JLabel l = new JLabel ("a<br>b"); 
    private JButton b = new JButton ("a<br>b"); 
    M (){ 
        setLayout (new GridLayout (2, 1)); 
        getContentPane().add (l); 
        getContentPane().add (b); 
        setDefaultCloseOperation (EXIT_ON_CLOSE); 
        setSize (200, 200); 
        setVisible (true); 
    } 
    public static void main (String args[]){ 
        new M (); 
    } 
}

JLabel honors HTML breakline, while JButton does not. 
 
(In fact, what I need is to break lines in JButton's text.  And I know 
there is a workaround by using a JLabel inside the JButton.) 
 
gcj-4.2-20060923-1 has the same problem.
