Question

我设置了100个线程来测试我的服务5分钟，这会引发一些IOExceptions（错误率约为10％）。以下是导致错误的代码段：

public class SoundServiceImpl implements SoundService {
   ... ...
   public String editSound(String url)){
   ... ...
   try {
        URL urlFile = new URL(url);
        stream = AudioSystem.getAudioInputStream(urlFile);
    } catch (UnsupportedAudioFileException e) {
        logger.error("UnsupportedAudioFileException, error happen when getting InputStream", e);
    } catch (IOException e) {
        logger.error("IOException, error happen when getting InputStream", e);
    }
    ... ...

这是日志：

ERROR 236112 --- [ULT-8-thread-31] c.a.a.provider.SoundServiceImpl: 
    IOException, error happen when getting InputStream

我的服务输入是一个音乐URL（“ http://rpg.hamsterrepublic.com/wiki-images/3/3e/Heal8-Bit.ogg”），我很困惑，为什么在高并发情况下我的服务会在这里抛出异常。谁能给我一些提示或可能的原因？
