I can confirm this.
A little investigation shows that there are two definitions for
`org-ditaa-jar-path':
- in =lisp/ob-ditaa.el=:
#+begin_src emacs-lisp
(defcustom org-ditaa-jar-path nil
"Path for the ditaa jar file."
:group 'org-babel
:type 'string)
#+end_src
This results in nil and so the error occurs.
- in =lisp/org-exp-blocks.el=
#+begin_src emacs-lisp
(defvar org-ditaa-jar-path (expand-file-name
"ditaa.jar"
(file-name-as-directory
(expand-file-name
"scripts"
(file-name-as-directory
(expand-file-name
"../contrib"
(file-name-directory (or load-file-name
buffer-file-name)))))))
"Path to the ditaa jar executable.")
#+end_src
On my machine this results in the correct path.
So the value of `org-ditaa-jar-path' depends on the loading sequence of
el-files.
A quick solution for OP would be to the set the path
#+begin_src emacs-lisp
(setq org-ditaa-jar-path "<path-to-ditaa-jar>")
#+end_src
I am not too deep into dependencies of org files, but ob-ditaa.el could
require org-exp-blocks and skip the definition of `org-ditaa-jar-path'.
Or vice versa.
