[kaffe] Cannot run AWT on Kaffe

I am actually getting the same problem as Kelvin when I run WidgetsDemo on
kaffe 1.1.8-pre on ARM:

> kaffe -Xkaffe-xlib-awt WidgetsDemo
java.lang.InternalError: Pointer class was not properly initialized

I am using the following config:
./configure --with-engine=intrp --with-kaffe-x-awt --disable-gconf-peer

I build with gcc 4.1.1.

Riccardo, since you didn't get the problem, can you let us know what
configuration you used and what target platform ? 

I build an x86 version too and that doesn't seem to have the problem.

I actually also got the same problems on a 1.1.7 version. Debugging it shows
something goes wrong when the first event dispatch thread is created and it
calls the function InheritableThreadLocal.newChildThread() in which it
executes Iterator keys = parentThread.locals.keySet.iterator(). Something
goes wrong in that iterator (parentThread != NULL).

Does anybody have any ideas, things I can try ?

When I add the -v option I get the following output leading upto the error

Loading java/awt/EventQueue.class(/usr/local/kaffe/jre/lib/kaffeawt.jar)
Loading java/util/AbstractMap$1.class(/usr/local/kaffe/jre/lib/glibj.zip)
Loading java/util/AbstractMap$1$1.class(/usr/local/kaffe/jre/lib/glibj.zip)
