Ошибка при перемещении класса в другой пакет

Есть метод проигрывания аудиоформата.

 public void soundClick(){
        try {
            clipClick = AudioSystem.getClip();
            InputStream input = new BufferedInputStream(getClass().getResourceAsStream("click1.wav"));
            AudioInputStream ais = AudioSystem.getAudioInputStream(input);
            clipClick.open(ais);
            clipClick.start();
            ais.close();
        } catch (LineUnavailableException e) {
            e.printStackTrace();
            JOptionPane.showMessageDialog(null,"Помилка під час програвання аудіо (1)");
            e.printStackTrace();
        } catch (UnsupportedAudioFileException e) {
            e.printStackTrace();
            JOptionPane.showMessageDialog(null,"Помилка під час програвання аудіо (2)");
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
            JOptionPane.showMessageDialog(null,"Помилка під час програвання аудіо (3)");
            e.printStackTrace();
        }

Все нормально работало, до тех пор пока я не переместил класс с этим методом в другой пакет. Теперь при воспроизведении звука выдает ошибку.

Почему поток закрыт?
