O problema é que não altera o idioma assim que eu altero o locale.

Só altera se eu reiniciar a aplicacao

private JLabel labelId;   

private JLabel labelNome;

labelId = new JLabel(AOP.getMessage("Codigo"));

 labelId.setBounds(10, 20, 70, 25);

 labelId.setHorizontalAlignment(SwingConstants.RIGHT);

 add(labelId);

labelNome = new JLabel(AOP.getMessage("Nome"));

 labelNome.setBounds(195, 20, 100, 25); labelNome.setHorizontalAlignment(SwingConstants.RIGHT);

 add(labelNome);
