             Summary: Forked channel requires udp.xml file
                 Key: JGRP-1827
                 URL: https://issues.jboss.org/browse/JGRP-1827
             Project: JGroups
          Issue Type: Bug
    Affects Versions: 3.4.1
         Environment: Android
            Reporter: Jim Thomas
            Assignee: Bela Ban
            Priority: Minor


An exception is thrown when creating a fork channel if the stack file name is something other than udp.xml (in my case main.xml):

final JChannel mainChannel = new JChannel("main.xml");
final ForkChannel mbChannel = new ForkChannel(mainChannel,
                        "main", "fork-mb");

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.
