I narrowed down where the problem arise and found the exact bugreport: https://github.com/clojure-emacs/orchard/issues/117#issuecomment-859987280
Unfortunately, I didn't get the solution 'one has to use ONLY the package "openjdk:jdk"'. What does it mean? Also, why openjdk removes javadoc, is it a bug or a correct behaviour?
