java.io.IOException：不支持标记/重置

这段代码不起作用。我已经准备好一堂课了，因为它可以找到here http://javafree.uol.com.br/topic-879623-Executar-wav.html，但音乐不起作用。我怎样才能解决这个问题？

private void lblCliqueMouseClicked(java.awt.event.MouseEvent evt){                                     
     lblClique.setText("achou");
     musica = new Som();
     boolean repetir = false; 
     FileInputStream arquivo = null;
     try {
         arquivo = new FileInputStream("musica.mp3");
     } catch (FileNotFoundException ex) {
         Logger.getLogger(TelaProjeto.class.getName()).log(Level.SEVERE, null, ex);
     }
     musica.tocar(arquivo, repetir);
} 

错误标记/重置不支持意味着您提供的输入流不支持设置标记并将流重置为该标记。要实现这一点，只需将 FileInputStream 包装在 BufferedInputStream 中（请参阅http://docs.oracle.com/javase/7/docs/api/java/io/BufferedInputStream.html http://docs.oracle.com/javase/7/docs/api/java/io/BufferedInputStream.html)

InputStream arquivo=null;
...
arquivo=new BufferedInputStream(new FileInputStream(...));
