Oleg Kalnichevski commented on HTTPCLIENT-1152:
-----------------------------------------------
One thing I do not quite understand. Why would there be anything other than
byte array in the memcache? In case someone was silly enough to have stuck some
arbitrary object in the memcache used by HttpClientCache throwing
ClassCastException seems perfectly reasonable.
