Bela Ban resolved JGRP-1684.
----------------------------

    Resolution: Won't Fix


Hi Rado,

as I mentioned on the PR, I don't want to fix this, because then I'd not be able to find out why msg.getSrc() ever returns null. I'd rather find out in which scenarios this can happen. Can you reproduce this ?

Also, this is an ACK, so no harm in discarding it, as the ACK will get resent.
