I had the same problem with the RequestFocusListener() not working on Linux, after following the discussion on http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5018574 I found that adding an invokeLater fixed it for now...

public class RequestFocusListener implements AncestorListener
{
public void ancestorAdded(final AncestorEvent e)
{
    final AncestorListener al= this;   
    SwingUtilities.invokeLater(new Runnable(){

        @Override
        public void run() {
            JComponent component = (JComponent)e.getComponent();
            component.requestFocusInWindow();
            component.removeAncestorListener( al );
        }
    });
}

public void ancestorMoved(AncestorEvent e) {}
public void ancestorRemoved(AncestorEvent e) {}
}
