I tried both on HP-UX 11.0 and SunOS 5.6 Generic_105181-14 sun4u sparc SUNW,Ultra-1.

Steps to reproduce.

1. Run Java2D demo.
   appletviewer /opt/java1.2/demo/jfc/Java2D/Java2Demo.html
2. Click on "Clipping" tab.
3. Select "Objects", "Clip 1".
4. Then select "Rendering Quality" and "AlphaComposite".
 
I get the following exception while running Java2D demo.

Exception occurred during event dispatching:
java.lang.IllegalArgumentException: Width (0) and height (0) must be > 0
