All Thai glyphs displayed as empty boxes on Solaris 8.

To reproduce:
0. Login on a Solaris 8 machine, any locale
1. Install JDK1.4 b26 (happened in b24 also)
3. Set Java path to correct path
4. Compile and run the enclosed test
   (Notice also, if set locale to th_TH, the fontpath is not set correctly, it'll give the following message:
Warning: Missing charsets in String to FontSet conversion
Warning: Missing charsets in String to FontSet conversion
Once set correctly as specified in /usr/openwin/lib/locale/th_TH/OWfontpat, the messages are gone)
5. Notice all the Thai glyphs show as rectangle boxes
6. Do the same procedure on a Solaris 7 machine, all the glyphs show as Thai glyphs
