Bug: org babel plantuml Java parameter is ignored [9.3 (9.3-elpa @ /nix/store/azm93cbq487szgddp5hhi4vp1q9ryyp7-emacs-packages-deps/share/emacs/site-lisp/elpa/org-20191203/)]

[Philipp Middendorf]

Hi guys,

I want to use the plantuml org-babel integration, as seen here:

http://eschulte.github.io/babel-dev/DONE-integrate-plantuml-support.html

I don't have a globally available "java" executable and from the 
source
code, it appears there is a ":java" parameter for org-babel to 
specify
an executable. Looking at the source code, however, it seems that 
this
parameter is never actually used (see org-babel-execute:plantuml 
in
ob-plantuml.el). Is this intentional? Since I'm not an elips guru, 
maybe
I just overlooked something. It, however, leads to me not being 
able to
use plantuml properly on my machine.

Regards
Philipp
