RSVP: passing up a message batch with some RSVP messages causes incorrect ordering ---------------------------------------------------------------------------------- Key: JGRP-1641 URL: https://issues.jboss.org/browse/JGRP-1641 Project: JGroups Issue Type: Bug Reporter: Bela Ban Assignee: Bela Ban Fix For: 3.3.1, 3.4 If we have a batch of messages 5-10 and message 7 is tagged as RSVP, then the logic in RSVP.up(MessageBatch) will do the following: * Iterate through the batch * If a message is marked as RSVP: remove it and pass it up (msg 7) * The pass the batch up * This means we'll pass up message 7 first, then messages 5,6,8,9,10 --> Incorrect order SOLUTION: * We cannot pass up RSVP messages directly * Instead, remember the RSVP IDs of the messages in the batch which were marked as RSVP * When done, send an RSVP response for each of these IDs
