FYI, you can customise any header arg globally. See manual page 16.3
Using Header Arguments.

I am not sure about this specific case. The PlantUML executable is
literally a wrapper around java call to jar. Below is the contents of
plantuml file in my system:

#!/bin/bash
gjl_package=plantuml
gjl_jar="plantuml.jar"
source /usr/share/java-config-2/launcher/launcher.bash

Unless it is any different on your side, the arguments for jar and
executable should be literally the same.

I feel that running headless mode in the ob-plantuml is deliberate. We
may not want users to change it. Otherwise, you are free to customize
java arguments in org-babel-default-header-args:plantuml

Thanks! Will fix.

Best,
