作成中のゲームにサウンドを追加しようとしていますが、サウンドをロードしようとするたびに Stream Closed Exception が発生します。なぜこれが起こっているのかわかりません。
サウンドをロードします:
public class WavPlayer extends Thread {
/*
* @param s The path of the wav file.
* @return The sound data loaded into the WavSound object
*/
public static WavSound loadSound(String s){
// Get an input stream
InputStream is = WavPlayer.class.getClassLoader().getResourceAsStream(s);
AudioInputStream audioStream;
try {
// Buffer the input stream
BufferedInputStream bis = new BufferedInputStream(is);

audioStream = AudioSystem.getAudioInputStream(bis); //!Stream Closed Exception occurs here
AudioFormat format = audioStream.getFormat();
// The length of the audio file

// Create a sound container
WavSound sound = new WavSound(samples, format, (int) audioStream.getFrameLength());
// Don't start the sound on load
sound.setState(SoundState.STATE_STOPPED);

私が得るエラーメッセージは次のとおり です。 218) で java.io.BufferedInputStream.read(BufferedInputStream.java:237) で java.io.DataInputStream.readInt(DataInputStream.java:370) で com.sun.media.sound.WaveFileReader.getFMT(WaveFileReader.java:224) ) stm.sounds.WavPlayer.loadSound(WavPlayer.java: 42) stm.STM.(STM.java:265) at stm.STM.main(STM.java:363)"
