This looks good and low-risk to me.
Could you, please, clarify why -headless in `org-plantuml-args' is not
enough and -Djava.awt.headless=true should be added despite it looks
redundant. Another question is why this option should be applied to jar
but not to plantuml launcher script. The commit dropping this option has
a link to discussion whether this argument is necessary and hard coded
in such way.
