regression - fails to load on ABCL

[avodonosov]

Something changed in clack since quicklisp 2014-07-14, and now clack and all the dependent libraries fail to load on ABCL

See diff between quicklisp 2014-07-14 and qlalpha 2014-08-23:
http://common-lisp.net/project/cl-test-grid/ql/qlalpha-2014-08-23-diff.html

The error:

SIMPLE-TYPE-ERROR : The value of BORDEAUX-THREADS::LOCK is #S(BORDEAUX-THREADS::MUTEX :NAME "Anonymous lock" :LOCK #<java.util.concurrent.locks.ReentrantLock java.util.concurrent.locks.Reent.... {B46184}>), which is not of type BORDEAUX-THREADS::MUTEX-RECURSIVE.

Strange that it happens during load time.

It is the same error that earlier appeared in datafly:
fukamachi/datafly#1

Thank you for reporting.

The error came from Clack.Middleware.Accesslog and datafly's came from datafly.logger.
It seems it's related to Log4CL. I still don't know why, though.

@export
(defvar *access-logger*
  (let ((logger (log:category '(clack middleware accesslog))))
    (log:config logger :own :trace)
    (log4cl:add-appender logger
                         (make-instance 'log4cl:this-console-appender
                                        :layout (make-instance 'log4cl:pattern-layout
                                                               :conversion-pattern "%m%n")))
    logger))

I think this problem has already been resolved after merging #95.
