New issue 238 by mcon...@gmail.com: Incorrect Exception Stack : WARN  
net.spy.memcached.transcoders.SerializingTranscoder:  Caught IOException  
decoding  bytes of data
http://code.google.com/p/memcached/issues/detail?id=238

I have blogged about it
http://mcondev.wordpress.com/2011/11/29/warn-net-spy-memcached-transcoders-serializingtranscoder-caught-ioexception-decoding-bytes-of-data/

My scenario is,
populate the entire table to memcached
get from memcached
While calling get if I type cast it to "List" instead of Object, I get a  
exception in the code populating the items to cache.
Please check the print stack trace code. Something really screwed here.

I have BBB and CCC extending from a class AAA. While I do a get in CCC,the  
stack trace shows up for BBB. Also in a random piece of code.
