cljr-rename-symbol: Doesn't work with Java 9

[em7]

Hello, I saw similar issue here but the solution "make sure you are running the latest versions" unfortunately did not help. I have a clean install of Emacs and all packages are freshly downloaded from melpa. Nonetheless I get this error.

This happens only when run on Java 9. I've tried with Java8_144 and it worked OK.

BTW Guys, thank you! You're doing a great job developing this project!

Expected behavior

When running cljr-rename-symbol command with cursor on a function name (both in a form calling a function or in a defn) I want the function to be renamed and all the calling code updated, assuming I have cider connected/jacked in.

Actual behavior

After I run the command with cursor on a function name, this is displayed in a minibuffer:

To perform this op the project needs to be evaluated.

Link to issue in the middleware repo: clojure-emacs/refactor-nrepl#206

Probably more people will run into this soon so I think it makes sense to leave this open in both repos.

refactor-nrepl >= 3.x.x is certainly support all JDKs.
