Can't change cursor using Java 1.4

Question

Hi all,
I wrote a program that worked while I had my Java Platform set to be 1.5. However, when I set my platform to be 1.4.2 (Java Hotspot) I encounter an error. What would be the best way to make the program work as I would like it to?
The code is:
  Toolkit tk = Toolkit.getDefaultToolkit();
  Cursor invisCursor = tk.createCustomCursor(tk.createImage(""),new Point(),null);
  this.setCursor(invisCursor);that is, I'm trying to hide the mouse cursor in my full-screen application.
When running the program in 1.4, the program works, but the mouse does not disappear and I get the following error:
  2006-12-05 14:52:21.935 java[744] *** NSThread: ignoring exception '*** -[NSCFArray objectAtIndex:]: index (2) beyond
   bounds (2)' that raised during delayed perform of target 0xa9a8bc20 and selector '_setNativeCursor:'What would be the best way to make my cursor invisible using Java 1.4?
Thanks!

Answer 1

Ok, here's my SSCCE that replicates my problem on my computer.
I am using a Mac (didn't get to try it on my PC, but regardless, I need this to work on a Mac), and the problem only occurs when I am using set my libraries to be Java 1.4.2.
The first option in hideMouse() simply fails to hide my mouse.
The second option fails to hide my mouse, and gives me the following error message:
  2006-12-06 10:02:27.785 java[394] *** NSThread: ignoring exception '*** -[NSCFArray objectAtIndex:]: index (2) beyond bounds (2)'
    that raised during delayed perform of target 0xa9a8bc20 and selector '_setNativeCursor:'It gives me this message only if I move my mouse, and repeats this message for as long as I move my mouse.
My goal is to hide my mouse.
Any help will be more than appreciated.
