Memcache Java API /deserialize issue

[Greg Whalin]

This is an error while deserializing your object as it comes out of 
cache.  This is a ClassCastException which means (from javadocs for 
ObjectInputStream.readObject()) "Class of a serialized object cannot be 
found.".

This is not a problem with the Memcached (client or server) but likely 
something with your code?
