Note that the latest debian packages store the JNI libraries in

I played a bit more with it. And as long as I don't use glib timer
callbacks I can play a bit with some windows and widgets.

One of the problem with glib Timer support is that kaffe doesn't
implement JNI_OnLoad() which java-gnome uses to store a pointer to the
JavaVM for use in its own callback funtions.

But even if I work around this I don't get that far when enabling the
glib timer. Often kaffe will say that all threads are deadlocked. This
seems to come from the fact that native method GtkMain() never returns.
