[jboss-jira] [JBoss JIRA] (JGRP-2090) JGRP000027: failed passing message up

[Bela Ban (JIRA)]

    [ https://issues.jboss.org/browse/JGRP-2090?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13267375#comment-13267375 ] 

Bela Ban commented on JGRP-2090:
--------------------------------

The change was done on purpose: all transports (UDP, TCP, TCP_NIO2, TUNNEL) etc have an ID of 75 (in 3.6) which is the ID assigned to TP.
The reason was that members which have TCP as transport can talk to members having TCP_NIO2 as transport.

Can you reproduce this error? And if so, how?

> The JGroups library is generating NullPointerExceptions when attempting to process incoming messages. From what I can tell this is due to it looking for an incorrect message header. 
> The TP object has a protocol id of 75 despite being a TUNNEL which ought to have an id of 24. The id is being correctly assigned to 24 at the Protocol.id member variable declaration, but is then subsequently changed to 75 by the TP.init method. This seems to have been caused by commit [6bc167f7e0181af32e1930935d8cf0efdc1e82f0|https://github.com/belaban/JGroups/commit/6bc167f7e0181af32e1930935d8cf0efdc1e82f0#diff-ce9d05d173a85bd820c6538f1e231645] which has the message "Added TP to jg-protocols.xml". If I backout this change to the TP.init method so as to not update the id then my application receives the incoming messages fine.
