«Помогите Артуру найти его ограниченный класс» или «как я могу сделать движок приложений Google счастливым»

где-то здесь я использую java.rmi.server.UID , что расстраивает GAE. После: только мои зависимости до костей, я в тупике.

(ns helloworld.core
  (:use ;[hiccup.core]
        [hiccup.page-helpers :only (html5 include-css)]
        [clojure.contrib.string :only (split)]
        [compojure.core :only (defroutes GET)]
        [hiccup.middleware :only (wrap-base-url)])
  (:require [appengine-magic.core :as ae]
            [compojure.route :as route
              :only (resources not-found) ]
            [compojure.handler :as handler :only (site)])
  (:gen-class :extends javax.servlet.http.HttpServlet))

 (defn index-page
  ([name]
     (html5
      [:head
       [:title (str "Hello " name)]
       (include-css "/css/style.css")]
      [:body
       [:h1 (str "Hello " name)]]))
  ([] (index-page "World")))

(def match-opperator
  { "add"      +
    "subtract" -
    "multiply" *
    "divide"   /})

(defroutes hello-routes
  (GET "/:f/*" [f & x]
       (index-page (apply (match-opperator f)
                          (map #(Integer/parseInt %)
                               (split #" " (:* x))))))
  (GET "/" [] (index-page))
  (route/resources "/")
  (route/not-found "Page not found"))

(def app
     (-> (handler/site hello-routes)
         (wrap-base-url)))

(ae/def-appengine-app helloworld-app #'app)

Я могу загрузить его на причале, и он отлично работает, после загрузки в dev-appserver я получаю следующее:

HTTP ERROR 500

ps: вот мой project.clj, если это помогает:
