Failed to allocate native stream - Leopard 10.5.4

Question

I've got this little class which runs off the EDT that plays sounds:
private class PlayThread implements ThrowableVoidAction {           
          public void act( Object o ){
               byte tempBuffer[] = new byte[512];
              try{
                   AudioInputStream     ain           = AudioSystem.getAudioInputStream( Notify.class.getResourceAsStream( (String)o ) );
                   AudioFormat               audioFormat = ain.getFormat();
                   DataLine.Info          info           = new DataLine.Info( SourceDataLine.class, audioFormat );
                   SourceDataLine          sDataLine      =(SourceDataLine)AudioSystem.getLine( info );
                    sDataLine.open(audioFormat);
                    sDataLine.start();
                    int cnt;
                    while( (cnt = ain.read( tempBuffer, 0, tempBuffer.length )) != -1 )
                         if(cnt > 0)
                              sDataLine.write( tempBuffer, 0, cnt );
                    sDataLine.drain();
                    sDataLine.close();
              catch (Exception e) {
                   System.err.println( "[Notify|PlayThread] act : " + e.getMessage() );
     }Works great in Linux/Windows XP/Vista, however, on the Apple 10.5.2+ JAva 1.6 build, it unfortunately spits out a "Failed to allocate native stream" in the catch block. Anyone have any ideas as to what the problem might be? Just a bad Apple JRE?
Thanks in advance!

Answer 1

In addition, a clip as follows fails as well:
import java.io.FileInputStream;
import sun.audio.AudioPlayer;
import sun.audio.AudioStream;
public class Test {
     String fileName;
     private Test( String s ){
          fileName = s;
     private void play(){
          try{
               System.out.println( "About to play stream" );
               AudioStream as = new AudioStream( new FileInputStream( fileName ) );
               AudioPlayer.player.start( as );
               System.out.println( "Stream executed" );
          catch( Exception x ){
               x.printStackTrace();
     public static void main( String [] args ){
          Test t = new Test( "sounds/msg.wav" );
          t.play();
}It outputs the final "Stream executed", but no sound is ever played..
