A DESCRIPTION OF THE PROBLEM :
The Windows Icons located in:
jdk1.7.0\jre\lib\resources.jar\com\sun\java\swing\plaf\windows\iconsare now blue instead of the yellow as in the last version i used (1.6_14).
Also, TreeClosed.gif and TreeOpen.gif are the same icon.

REGRESSION. Last worked in version 6

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create a JFileChooser and view the icons.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I'd expect Icons for directories in Windows to be yellow, and a separate icon for TreeClosed.gif and TreeOpen.gif
ACTUAL -
Colours are predominantly blue and the TreeOpen/Closed icons are identical.

REPRODUCIBILITY :
This bug can be reproduced always.
