rt.jar / Key.Adapter.class

Question

Googling a lot, I found nothing about the problem with this specific class (Key.Adapter.class), but there are a lot of topics about rt.jar of course, and I tried so many things to correct it, I tried to set the location of rt.jar and installed the plugin Java Source Attacher (didn't work). I reinstalled Eclipse as well, but the error still occurs:

What's strange about this is that I didn't make any change at anything related to the library (if I did, that was not intentional). I was just moving some things but nothing related to the libraries. The console returns NullPointerException at line 190:

name2.addKeyListener(new KeyAdapter() {
            @Override
            public void keyPressed(KeyEvent arg0) {

                int key = arg0.getKeyCode();

                if (key == KeyEvent.VK_ESCAPE) {

                    //Custom button text
                    Object[] options = {"Sim",
                                        "Não"};

                        int choice = JOptionPane.showOptionDialog(frame1,
                        "Deseja sair do jogo?",
                        "Mensagem",
                        JOptionPane.YES_NO_CANCEL_OPTION,
                        JOptionPane.QUESTION_MESSAGE,
                        null,
                        options,
                        options[1]);

                        if (choice == 0) {

                            System.exit(0);
                }
            }
        }
        }

        );

To make a new project will be that way as well. And the Window Designer / Run doesn't work as well.

Is there another possibility to make rt.jar useful again?
