When running a simple app that gets a Sequencer object and exits, OpenJDK will
create the object and not exit while sun-java6-jre (version 6-07-4ubuntu2)
creates the object and properly exits. The proper behavior is the one Sun's
java exhibits.

Sample program (also attached):
import javax.sound.midi.*;

public class MusicTest1 {
    public void play() {

        try {
            Sequencer sequencer = MidiSystem.getSequencer();
            System.out.println("Successfully got a sequencer");
        } catch(MidiUnavailableException ex) {

    public static void main(String[] args) {
        MusicTest1 mt = new MusicTest1();
        System.out.println("After play");
