[jboss-jira] [JBoss JIRA] (JGRP-1827) Forked channel requires udp.xml file

[Bela Ban (JIRA)]

    [ https://issues.jboss.org/browse/JGRP-1827?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12962192#comment-12962192 ] 

Bela Ban commented on JGRP-1827:
--------------------------------

Your config is incorrect: FORK cannot define its fork stacks inline. You need to point to a separate config file which defines the stacks, e.g.:
{code:xml}
<FORK config="/home/bela/fork-stacks.xml"/>
{code:xml}

That is, unless you changed this in your port to Android.

I attached main.xml, fork-stacks.xml and bla2 which demonstrate how this works.
Please close this issue if your problem is resolved.

> If I have the stack named udp.xml then the exception is not thrown and everything works as expected.  If I make a copy of main.xml named udp.xml (so both files are present) the exception is not thrown and everything works as expected.
