font.point change during runtime in a JTextField

What's wrong with using setFont, an if condition and the appropriate listener, in this case a CaretListener?

final JTextField field = new JTextField();

field.addCaretListener( new CaretListener() {

Font big = new Font("Verdana", Font.PLAIN, 13);

Font small = new Font("Verdana", Font.PLAIN, 9);

public void caretUpdate(CaretEvent e) {

if(field.getText().length() > 30) {

field.setFont( small );

} else {

field.setFont( big );

}

}

} );
