Extreme Java When vanilla Java is not enough

IOException when loading a sound/midi from a JAR/ZIP archive

I have a MIDI file in a JAR archive. If I try to play it with the Sequencer class, I got an exception: "java.io.IOException: mark/reset not supported". I've found this related bug. I don't like workarounds (all bugs must die), but I developed this one:

public static InputStream loadStream(InputStream in) throws IOException {
  ByteArrayOutputStream bos = new ByteArrayOutputStream();
  byte[] buf = new byte[1024];
  int c;
  while ((c = in.read(buf)) != -1) {
    bos.write(buf, 0, c);
  }
  return new ByteArrayInputStream(bos.toByteArray());
}

With this method, I encapsulate the "unresetable" stream into a "resetable" ByteArrayInputStream.
