      Description

      Name: izR10247 Date: 11/18/2003



      Current J2SE 1.5 b28 spec states following:
      "
      SetLoopEndPoint

      public void setLoopEndPoint(long tick)
      ...
      Throws:
          IllegalArgumentException - if the requested loop point cannot be set,
      usually because it falls outside the sequence's duration or because the
      ending point is before the starting point".

      However current implementation of MidiSystem.getLoopEndPoint() does not
      generated expected IllegalArgumentException. This bug causes failure of
      new JCK test:

      api/javax_sound/midi/Sequencer/index.html#Loop[Loop003]

      To reproduce this bug please run test 'MyTest' using script 'MyTest.sh' below:

      =============== MyTest.java source begin ===============
      import javax.sound.midi.*;
      import javax.sound.sampled.AudioPermission;

      public class MyTest {

          public static void main(String argv[]) {

              Sequencer seq = null;
              MidiDevice.Info[] infos;
              try {
                  infos = MidiSystem.getMidiDeviceInfo();
                  for(int i=0;i<infos.length;i++) {
                      if(MidiSystem.getMidiDevice(infos[i]) instanceof Sequencer) {
                          seq=(Sequencer)MidiSystem.getMidiDevice(infos[i]);
                      }
                  }
                  seq.open();
                  System.out.println("Revelead sequencer: " + seq.getClass().getName());
                  seq.setLoopEndPoint(1);
                  try{
                      seq.setLoopStartPoint(2);
                      System.out.println("Expected IAE does not generated!");
                  } catch (IllegalArgumentException iae) {
                      System.out.println("Expected IAE:" + iae);
                  }
              } catch (MidiUnavailableException mue) {
                  mue.printStackTrace();
                  System.out.println("MidiUnavailableException was thrown: ");
              }
          System.exit(0);
          }
      }
