A DESCRIPTION OF THE PROBLEM :
When drawing a rotated BufferedImage using Graphics2D
tranformation mechanism, the colors are wrong on Linux. The
exact same code works flawlessly an Solaris and MacOS X
systems.This bug is present in JDK 1.4.0 as well.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Run the code example below

EXPECTED VERSUS ACTUAL BEHAVIOR :
I expect to see the image specified on the command line
displayed twice; once with no rotation, and one rotated by
90 degrees. The rotation works, but the rotated image is
displayed in incorrect colors. On Solaris (Sparc) and MacOS
X the code works as expected.

REPRODUCIBILITY :
This bug can be reproduced always.
