Incorrect Exception Stack : WARN net.spy.memcached.transcoders.SerializingTranscoder: Caught IOException decoding bytes of data

[GoogleCodeExporter]

I have blogged about it
http://mcondev.wordpress.com/2011/11/29/warn-net-spy-memcached-transcoders-seria
lizingtranscoder-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.

Sorry guys, my hibernate pojo's had a lot of inheritance associated with it. 
And the super classes were not serialized, and if I would have serialized it I 
would have compromised performance big time.

The exception here is valid. Please close this bug.

This is a spymemcached 
(http://code.google.com/p/spymemcached/issues/detail?id=222) issue, bug does 
not belong here.
