Use Windows NT Terminal Server (also known as hydra)
Login to the server from Windows NT or Windows 95 client
set JAVAHOME=e:\jdk1.2
set JAVA_HOME=e:\jdk1.2
set CLASSPATH=.
cd e:\jdk1.2\demo/jfc/table
java TableExample4

This results in the message "The application has performed an illegal operation"
If you use MKS toolkit korn shell, you get segmentation violation

Cannot run any applications that need to bring a GUI
All console applications are fine.

The cutomer tried the suggested workaround of setting the JAVA_FONTS environment vairable. It did not work.

Here is the simplified code as below to isolate the problem. Using
JDK 1.3 beta-O, with WTS (Windows terminal Server) v1.8, the failure still occurs. The problem is known to occur on JDK1.2.1, JDK1.1.2, and JDK1.3 beta.

 Opens empty frame for 1 second, then get this error:
