Now that you mention it, I do remember some fuss long time ago about headless requiring X11. Hmmm. That means that any attempt to use headless is definitely out of bounds for this patch. Maybe the best way for this patch is then to exclude the java.desktop module for iOS and Android in Modules.gmk.

But I'll look into headless once more to see if I can figure out if it *really* needs X11 or if it's just some sloppy programming.
