** Description changed:

  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.
+ 
+ 
+ Update: as pointed out by Man Yuan in Comment#4, the font paths for wqy-zenhei in fontconfig.propertie sneeds to be updated as well. The font file suffix has been changed to ttc after the upgrade to 0.8.34 last year.
