    System clipboard on Mac OS X


      I'm having troubles getting data from the clipboard on Mac OS X.
      What I want to achieve: printing new data that was entered into the clipboard. [if it is text based]
      The problem: I'm tracking changes in system clipboard by tracking clipboard ownership changes, my idea works fine on both Windows and Linux [openSuse] however on Mac OS X my app can't print the content of the clipboard until it gets focus.
      import java.awt.Toolkit;  
      import java.awt.datatransfer.*;  
      import java.io.IOException;  
      public class ClipboardListener extends Thread implements ClipboardOwner {
          Clipboard systemClipboard = Toolkit.getDefaultToolkit().getSystemClipboard();  
          public void run(){  
              Transferable selection = systemClipboard.getContents(this);  
              while (true) {}
          public void gainOwnership(Transferable t){ 
               try {this.sleep(100);} 
               catch (InterruptedException e) {e.printStackTrace();}
              systemClipboard.setContents(t, this);  
          public void lostOwnership(Clipboard clipboard, Transferable contents) {
               String s;
              try {System.out.println((String) clipboard.getData(DataFlavor.stringFlavor));} 
              catch (UnsupportedFlavorException e) {} 
              catch (IOException e) {}
      public class myApp {
           public static void main(String[] args){
                ClipboardListener listener = new ClipboardListener();
      What I'm missing/doing wrong?
