camel-netty consumer with multicast address

[samel <sa...@lmco.com>]

Hello all,

I'm using Camel 2.11.0 and trying to use camel-netty to listen on a true
multicast UDP address (224.0.0.0 through 239.255.255.255 -
http://en.wikipedia.org/wiki/Multicast_address).  I don't see any exception
but I'm unable to get an messages through either. However, if I use
non-multicast addresses such as localhost or my own IP, things seem to work.
Does anybody have experience with this and any pointers?  Thanks in advance.

Here are my observiations
