Re: [jgroups-dev] Bug in ENCRYPT?

Is this reproduceable ?

If so, can you reproduce it with JGroups version 3.x (e.g. 3.2) ? 
JGRP-1321 may have fixed this.

Also note that I don't support 2.12.x on a community basis:

Node 2 joins the cluster and gets an encryption key from node 1. Things look good. Node 1 then shuts down and restarts after a while. Node 2 is the co-ordinator now. When Node 1 restarts it is unable to send messages to Node 2. The jgroups logs on Node 2 show the following:
