Race conditions can have NAKACK try to send to hosts don't have a receiver window yet -------------------------------------------------------------------------------------- Key: JGRP-1027 URL: https://jira.jboss.org/jira/browse/JGRP-1027 Project: JGroups Issue Type: Bug Affects Versions: 2.6.12 Reporter: Gray Watson Assignee: Bela Ban Priority: Minor Fix For: 2.9 Attachments: NAKACK.java.patch, NAKACKEarlyTest.java, NAKACKEarlyTest.java We have seen NPEs in NAKACK trying to send to hosts who do not have a registered receiver window. I'd like to apply the attached patch which does a better job of creating a receiver window on the fly in these circumstances. One issue what the sequence number should be initialize to -- the patch uses 0 which has worked for us. Thanks,
