(use 'clj-stacktrace.repl) in :repl-options :init causes ac-nrepl.el to hang caching JVM class names

[mjwillson]

Apologies as I'm not sure if the problem is with clj-stacktrace or with https://github.com/purcell/ac-nrepl, but it's a bit of a showstopper for using this in the REPL in emacs so thought I'd mention it.

After substituting (use clj-stacktrace.repl) for (use 'clojure.stacktrace) in my .lein/profiles.clj :repl-options :init, ac-nrepl suddenly starts to hang when I nrepl-jack-in on "Caching JVM class names". Only restarting emacs fixes it.

Using lein 2.0.0 with latest nrepl.el and ac-nrepl.
