      Description



      Name: dfR10049 Date: 09/07/2000




      javax.sound.sampled.AudioSystem.getAudioInputStream(URL url) incorrectly throws
      IOException if file encoding is different from ascii and url points
      to .aif file. It works good with this url in the ascii encoding
      and with another audioformat files in the Cp037 encoding.



      This is the test demonstrated the bug:

      -------------------------------------
      import javax.sound.sampled.*;
      import java.io.*;
      import java.net.*;

      public class SoundTest {

          public static void main(String args[]) {

              URL soundurl = null;
              BufferedWriter log = null;
              CharArrayWriter traceWriter = new CharArrayWriter();

              try {
                  log = new BufferedWriter(new
                          OutputStreamWriter(System.out, "ASCII"));
                  String soundname = new String (args[0].getBytes(), "ASCII");
                  soundurl = new URL(soundname);
                  log.write("url: " + soundurl + '\n');
              } catch (IOException e) {
                  try {
                      log.write("unexpected exception: " + e + '\n');
                      log.flush();
                  } catch (IOException e1) {
                  }
                  System.exit(1);
              }
          
              boolean thrown = false;

              try {
                  AudioSystem.getAudioInputStream(soundurl);
              } catch (UnsupportedAudioFileException e1) {
              } catch(IOException ioe) {
                  ioe.printStackTrace(new PrintWriter(traceWriter));
                  thrown = true;
              }
              
              try {
                  if (!thrown)
                      log.write("no exception" + '\n');
                  else {
                      log.write("IOException thrown" + '\n');
                      log.write(traceWriter.toString());
                  }
                  log.flush();
              } catch (IOException e) {
              }
          
          }
      }
