The problem:
The testcase is in /share/esc/1-9895956/
you can reproduced it with jdk 1.4.2_5 or later with patch 109147-34.
You will see the color problem. The problem looks like a "color flashing" problem.
But it is not. The problem happens on all graphics cards, if you set it to 8 bit
only. With 1.4.2_2 or older, you do not see this problem. Without 109147-34, even
with 1.4.2_7 you do not see this problem either.

To run the testcase:
setenv JDKHOME /net/koori.sfbay/onestop/jdk/1.4.2_08/latest/binaries/solaris-sparc/bin
1. compile java program
$JDKHOME/javac colorProblem.java
2. run the program
$JDKHOME/java colorProblem
3. move mouse focus to app, then move away, you will see it.
