Metal L&F hardcodes PropertyPrefix for gradients

FULL PRODUCT VERSION :
java version "1.5.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-b64)
Java HotSpot(TM) Client VM (build 1.5.0-b64, mixed mode, sharing)


ADDITIONAL OS VERSION INFORMATION :
Linux computer 2.6.5 #1 Mon May 24 13:55:25 MDT 2004 i686 Pentium III (Coppermine) GenuineIntel GNU/Linux


A DESCRIPTION OF THE PROBLEM :
Metal L&F classes hardcode the propertyPrefix when accessing gradients instead of using the getPropertyPrefix function making it more difficult to override the gradient colors when extending UI Classes.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Extend MetalButtonUI ( or any other UI that uses gradients) and override the getPropertyPrefix() function to return a new PropertyPrefix. Add new Gradient using UIManager.put(Object key, Object value).

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Assigning new UI should use the gradient for that begins with the new PropertyPrefix.
ACTUAL -
Component will still use the original gradient.

REPRODUCIBILITY :
This bug can be reproduced always.
