Public bug reported:

OpenJDK does not display Chinese (or CJK) characters correctly. It
appears that all Han glyphs were displayed using wrong metric, and is
only half to 1/3 of the actual EM width.

A screenshot is attached to illustrate the problem. To reproduce, select
"OpenJDK Java 6 policy Tool" from the setting sub-menu, then select menu
File\Open and navigate into a folder with Chinese name.

Notice that the Chinese folder name "中文目录" in the top file name box is
only half-width, but the Chinese subfolder names in the left panel are
fine.

This was also reported previously in Ubuntu Chinese forum (in Chinese),
see http://forum.ubuntu.org.cn/viewtopic.php?f=8&t=221482

Creating a link in /usr/lib/jvm/java-6-openjdk/jre/lib/fonts/fallback
folder does not solve the problem. Also, OpenJDK does not follow the
fontconfig settings.
