The shade of some JCK fonts look too light when antilaiasing is turned on.

To reproduce:

1. Install additional language to the system
2. Launch Font2DTest demo
3. Select CJK Unified Ideographs
   A lot of glyphs are very dim

Note: this is also reproducible in WinXP 32bit

Three snapshots are attached, for jdk 1.4.2, 1,5, and 1.6.
This doesn't seem to be introduced from Mustang, if select SimSun or SimHei for instance, or any logical fonts, size 12 or 14, all glyphs appear very blurry. Same with Katakana and Hiragana.
