The current reference implementation (JDK 1.4.2beta, build b11)
of the javax.sound.sampled.Mixer.getTargetLineInfo(Line.Info info)
throws unspecified ArrayIndexOutOfBoundsException. This behavior
seems quite reasonable but is not specified:
------------------ example code begin --------------------------
import javax.sound.sampled.Mixer;
import javax.sound.sampled.Line;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.TargetDataLine;

public class MyTargetDataLine{
    public static void main(String args[]){
        try {
            Mixer.Info[] mixers;
            mixers = AudioSystem.getMixerInfo();
            Mixer myMixer = AudioSystem.getMixer(mixers[0]);
            myMixer.open();
            Line.Info[] infos = myMixer.getTargetLineInfo();
            System.out.println("Length is: " + infos.length);
            TargetDataLine tdl = (TargetDataLine)myMixer.getLine(infos[0]);
            myMixer.close();
        } catch (Exception e){
            System.out.println("Exception: " + e);
        }
    }
}
