Attachment: MessageTest.java
Attached the sample program used too test this issue
> TCP/TCPPING creates too many unnecessary connections
> ----------------------------------------------------

> Key: JGRP-26
> URL: http://jira.jboss.com/jira/browse/JGRP-26
> Project: JGroups
> Type: Bug
> Versions: 2.2.8
> Environment: Java 1.4.2
> Reporter: B.S.Navin

> A simple program using JGroups with a TCP/TCPPING/FD combo at the bottom of
> the stack, creates too many unnecessary connections.
> The program just creates a channel and registers a message listener that just
> printss the message.
> When this program is run, it creates 2 TCP connections - One to the port of
> the TCP protocol of this program & the other from the prot of the TCP
> protocol of this program.
> These 2 connections seem to be created when a ping message is sent to the
> hosts in the initial_hosts list of the TCPPING protocol. The target address
> should be checked and the message should automatically be processed within
> the same stack without sending it on the network, if the dest. address is
> same as this.
> Also, the FD protocol sends a message to its peer and receives a response.
> This causes 2 more connections to be created. Whereas the same connection
> could have been used to send the response message.
