It seems to me that the requested function are implemented in
libraries/javalib/java/awt/

which is part of GNU classpath, while I'm using the implementation
from libraries/javalib/awt-implementations/kaffe/java/awt/,

So the question is: to have the supoprt for swing, do I need
to use GNU classpath: the problem is that, from what I understand,
if I remove 
--without-classpath-gtk-awt
from configuration, I will need GTK, which is not present
in my system: so to use swing, do I need to install GTK?

thanks
giammy
