Try README CLJ call Elisp function demo error

[stardiviner]

When I try the README Clojure call Elisp function demo, I got error:

Call Elisp from Clojure:

;; emacs lisp:
(require 'clomacs)
(clomacs-httpd-start)

;; clojure:
(use 'clomacs)
(clomacs-defn emacs-version emacs-version)
(println (emacs-version))

2. Unhandled java.lang.ExceptionInInitializerError
