[swing] JDialog.dispose() not working.

So I have a dialog with a "Cancel" button.
The cancel button simply calls this.dispose() on actionPerformed().

Everything works fine until I set the dialog as modal.
If I use this.setModal(true); the dialog is modal (which is what I need) however the cancel button doesn't close the dialog anymore.

Any ideas?

Works fine for me.
Here's my code:

Code:

---

import java.awt.event.*;

import javax.swing.JButton;
import javax.swing.JDialog;


public class Test extends JDialog implements ActionListener{
       
        private static final long serialVersionUID = 1L;

        public static void main(String[] s){
                Test t = new Test();
                t.init();
               
        }
       
        public void init(){
                JButton b = new JButton("Cancel");
                b.addActionListener(this);
                add(b);
                pack();
                setModal(true);
                setVisible(true);
        }

        @Override
        public void actionPerformed(ActionEvent e) {
                this.dispose();
        }

}
