Grahame Rogers commented on JGRP-1252:
--------------------------------------

Hi,
I have written a test class called ChatTestManager attached in JgroupsTest.zip, which encapsulates the problem I originally reported. In short, this starts a GR, then 4 clients. It then kills 1 client, then restarts the GR and adds another client. At this point the issue should be replicated and will log out a report. I have noticed that sometimes the new client fails to start properly so the test sometimes incorrectly logs failure, but this is obvious as one of the members logged will be shown as null. This project should be self contained, so you just need to unzip and call run.bat. Please note that this needs to be run on a network and not stand-alone. The class is fully commented but if you have any questions, please shout

> I run the chat demo app that was shipped with an older version of Jgroups. Using tcp transport, with tcpgossip for discovery I start up 2 instances of the chat application. I then restart the gossip server and also another instance of the chat application. The 3rd instance of the chat application receives a view update (membershipListener.viewAccepted) only the logical name of one of the 2 previous instances of the chat client is incorrect. I have detailed the results in: http://old.nabble.com/TCPGossip-Discovery-Issue-td30227966.html
> I will attach the test client to this bug report.
