Hi Sun,

Thanks for your patience. This looks quite straight-forward. I don't use
or have plantuml so I'm in a poor position to test.

However, I can use google, and it seems that -Djava.awt.headless=true
just uses Java for some graphics operations which are normally delegated
to the system graphics stack.

This seems rather safe to me, and so I'd be inclined to take your word
that this is a beneficial change and merge the patch.

All the best,
Timothy
