Bela Ban commented on JGRP-753:
-------------------------------

Sorry, I won't change this, for my arguments put forth above. This would be a change that introduces overhead to each message for a very special case in your application. 
You can generate the object the first time you de-serialize, attach it to an application-provided header and then fetch it from that header, if you need to prevent duplicate de-serialization.
