Test set up:
jdk build: b56
GS version:GS06

Steps to reproduce:
1)Login to any platform(solaris/windows) in hindi / Thai locale
2)Use GS and execute any of the text editing components for example:
sh run_gs.sh -jdk:<jdk1.5.0-home-path> ../../src/GS/LigatureTest/JTextAreaLTest1.java
3)Try inputting the hindi/thai characters(as per the locale in which you have logged in)
4)Observation: As the characters are typed the entire text dissapears. Just the cursor movement can be seen.
This happens even with the input dialog that is available when executing JDialog.

Other related testing:
1) Login with hindi /thai locale on any platform
2) Execute the Notepad/Stylepad demo applications that are been provided under the jdk1.5.0/demo/jfc/ directory , using the command for example: java -jar Notepad.jar
3)Input the hindi / thai characters
4)Observation:
 -After typing few characters, press Enter. As you type in characters the glyphs are not seen on the text component. Only after pressing 'Enter' the entire line that you typed becomes visible
-Even when just pressing Enter key the following exception was thrown
