Technically speaking AWT uses various X11 libs:
libXp, libXt, libXext, libXtst, libXmu, libX11, libSM, libICE.

If your server setup ever needs creating graphs, images, charts, etc...
you will definately need X11.

Even if your server never does any imaging, i think a correct
installation should have all dynamic object (.so.* files) 
dependencies in place before any serious use.
