Hello!
I’ve noticed that at least ditaa and plantuml fail to evaluate with babel.
While for ditaa I can override :java list item with something like
(setq org-babel-default-header-args:ditaa
'((:results . "file")
(:exports . "results")
(:java . "-Dfile.encoding=UTF-8 -Djava.awt.headless=true")))
However plantuml is handling differently. Curiously enough it runs just fine
without stdin/stdout redirection from the command line. However if I tried to
use input/output redirection like in ob-plantuml.el , it complains like the
following: Exception in thread "main" java.lang.InternalError: Can't connect
to window server - not enough permissions.
I propose to add by default “-Djava.awt.headless=true” to all “language”
handlers supported by org-babel. I think it won’t hurt and will make working
from CLI more enjoyable out of box.
