Two methods return time length of Midi Sequence in Java Sound API:
  javax.sound.midi.Sequencer.getTickLength()
  javax.sound.midi.Sequence.getTickLength()

But these methods return different values for same sequence in
JDK RI(1.4.1-beta-b06) and spec does not state anything that could
imply the tick length may differ for particular Sequencer. Note, this
bug is similar to bug#4659445 but the differrence between the values
is much greater and I guess it is duplicate of #4659445.

This bug causes failure of new JCK test:
  api/javax_sound/midi/Sequencer/index.html#Sequencer

To reproduce the bug run the following test with JDK build 1.4.1-beta-b06:
------------------------------- test.java --------------------------------
import javax.sound.midi.*;
import java.io.*;

public class test{
    public static void main(String args[])
    {
        boolean failed = false;
        File seqfile;
        Sequencer seq = null;
        Sequence midiData = null;
        
        try {
            seq = MidiSystem.getSequencer();
            seq.open();
            seqfile = new File(".", args[0]);
            midiData = MidiSystem.getSequence(seqfile);
            seq.setSequence(midiData);
            if (seq.getTickLength() != midiData.getTickLength()) {
                System.err.println("Sequencer TickLength was : "
                        + seq.getTickLength());
                System.err.println("Sequence TickLength was : "
                        + midiData.getTickLength());
                failed = true;
            }

        } catch (MidiUnavailableException munEx) {
            munEx.printStackTrace();
        } catch (InvalidMidiDataException invmEx) {
            invmEx.printStackTrace();
        } catch (IOException ioEx) {
            ioEx.printStackTrace();
        }
    
        if( failed ) {
            System.err.println("Test failed!");
        } else {
            System.out.println("OKAY");
        }
        System.exit(0);
    }
}
