[jboss-jira] [JBoss JIRA] Updated: (JGRP-1150) NakAckHeader: streamline serialization (remove 'sender' field ?)

NakAckHeader: streamline serialization (remove 'sender' field ?) ---------------------------------------------------------------- Key: JGRP-1150 URL: https://jira.jboss.org/jira/browse/JGRP-1150 Project: JGroups Issue Type: Task Reporter: Bela Ban Assignee: Bela Ban Fix For: 2.10 The 'sender' field is only used for retransmissions, but do we ever use it to request a retransmission on behalf of someone else ? If not, we could use msg.getSrc() instead ! Currently, an address (UUID) uses 18 bytes, so we would save 18 bytes per multicast message ! This is good as long as we don't have canonicalization of addresses yet
