Can't display chinese and japanese at the same time (Urgent!!!!)

[S Dan]

Ok, the following program tries to display a string that contains mostly japanese characters along with few chinese characters.
When I try "java I18NTest zh ZH" it shows all japanese and chinese characters properly except one.
When I try "java I18NTest ja JA" its shows the japanese fine but messes up the chinese characters.
What do I have to do so that it displays all japanese and chinese characters properly? Following is the java code and the .properties files (both the properties files are same though). I'm sure that the problem has nothing
to do with system fonts as there is a third party java application that shows those characters properly on my machine. Any help will really be appreciated.
Thanks.
