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

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,
