I don't think Linux supports binding to an interface for multicast.
Multicast still works, you just can't bind it, instead you setup your
routing table to make sure you route it the way you want.
the other way you can do is setup static memberships, where you define
your tomcat instances instead.

no all operating systems support a bind address for multicast sockets
