[NREPL-46] nREPL crashes when required more than one time with :reload-all Created: 21/Dec/13  Updated: 21/Dec/13

Irrelevant, but the provided test case project is for CounterClockWise on Eclipse. Although it should run just fine with vanilla lein.

When the namespace "clojure.tools.nrepl.server" is required more than once with :reload-all option, nREPL crashes. Accrding to current info it occures because some protocol instances get re-evaluated and are no longer the same JVM classes as they were before reload-all.

Steps to reproduce the bug in CCW:
1) Import the project into the workspace
2) Go into the core.clj
3) Click Clojure -> Load file in REPL
4) After the evaluation is complete, try evaluating (+ 1 2) in the repl. You should see no response at all.
5) Try writing something with letters, like "nrepl". The autocompletion will try and freeze and fail with the above exception.
6) Play around more to get a full hang or kill the REPL/Java to revive Eclipse.

Upon trying CCW autocompetion, the following exception occures, what might give some hint as to why:

Exception in thread "nREPL-worker-2" java.lang.IllegalArgumentException: No implementation of method: :send of protocol: #'clojure.tools.nrepl.transport/Transport found for class: clojure.tools.nrepl.middleware.pr_values$pr_values$fn$reify__1283
