Then the problem probably lies with the program which throws the
exception. Yes, I know it works in a Windows environment, but even with
Java it is possible to write non-portable code. Is the source code 
available? Try writing a simple, "Hello World!" program using AWT for
comparison, e.g.,

import java.awt.*;

public class HelloWorld {
    public static void main(String[] args) {
        Frame f = new Frame();
        f.add(new Label("Hello World"));
        f.pack();
        f.setVisible(true);
    }
}
