clip animations with Alpha Composite option. This bug does not occur in merlin and it occurs in kestrel and firefly.

How to reproduce the bug:
Install the jdk. Goto demo directory of the jdk installed. Goto jfc - > java2D dirs.
Give 'java -jar Java2Demo.jar'. Choose clip tab and double-click clip animations.
Choose Alpha Composite option and make sure that both object and clip buttons are selected. Check the prompt for the above exception.
