Anyone tried the multicast support yet?

I'm wondering if anyone on this mailing list has tried the multicast and
other socket-channel changes yet? While somewhat niche, many developers
have been being asking for this feature for many years. If you are
willing to try it out then the javadoc, source code, and binaries are
available via the project page . To re-cap, the updates allow a
DatagramChannel's socket join multicast groups so that multicast
datagrams can be received. We've used the opportunity to update the
multicast support to the most recent IEFT standards and specifically
source-specific multicast (IGMPv3 and MLDv2). Implementation changes
include support for the new IPv6 stack on Windows Vista, something that
would also be useful to get feedback on.
My motive for asking for feedback at this time is that we would like to
push the changes for this part of the API to the jdk7 repository soon.
The reason for this is make it easier to merge and stay in sync with
other bug fixing other in the channels area. Also, there is other
on-going work that has dependencies on the changes in the API and
implementation changes in the nio repository.
If you are interested in trying it then there is some sample code in the
$JDK_HOME/sample/nio/multicast directory that exercises the API. This
also demonstrates inclusive and exclusive mode filtering for those
interesting in trying that out.
