The code in 
libraries/javalib/awt-implementations/kaffe/java/awt/Toolkit.java looks 
like this:

static {
         final String AWT_NATIVE_LIBRARY = 

The idea is to check a proprty that tells Kaffe which native library to 
load for the native implementation of the AWT code. In your case, I 
guess, you'd need to add -Dkaffe.awt.nativelib=xawt (assuming that's 
what you compiled against) to your command line invocation. You should 
also get the same result by just using

kaffe -Xkaffe-xlib-awt HelloWorld

see the -Xkaffe-*-awt parameter handling code in kaffe/kaffe/main.c.
