+1 to changing the name/directory.
-100 to changing the order of where it's looked for instead.
All resource lookups should use the normal rules for finding resources.
Don't change standard behavior without a *very* good reason.
Doing anything special (like META-INF/_internal/jgroups-udp.xml) is
and will cause support issues down the road.
Using config/jgroups-udp.xml is standard, and would be immediately
understood by anyone.
