[jboss-jira] [JBoss JIRA] (JGRP-1781) Message: write/read the payload last when marshalling

Message: write/read the payload last when marshalling ----------------------------------------------------- Key: JGRP-1781 URL: https://issues.jboss.org/browse/JGRP-1781 Project: JGroups Issue Type: Enhancement Reporter: Bela Ban Assignee: Bela Ban Fix For: 3.5 When (un)marshalling a message, we process the fields in this order: # Sender and receiver addresses # Flags # Payload # Headers I'd like to change this to move processing of the payload to the end because * If payload refers to a different buffer (JGRP-1773), then we don't need to read the bytes, but currently have to skip N bytes to read the headers. If the payload was at the end, this wouldn't be needed * Once we use NIO.2 and gathering writes, we'd pass a couple of buffers to the socket write and therefore it's simpler if the payload is written last. Ditto for scattering reads.
