Just as background to this. The javadoc is clear that support for 
source-specific multicast (both include mode and exclude mode) is 
optional. The changes in this webrev just mean that the block or 3-arg 
join methods will throw UOE. The return JNI_FALSE in 
canIPv6SocketJoinIPv4Group0 just means that DatagramChannels to IPv6 
sockets can't join IPv4 groups, again something the javadoc is clear is 
not guaranteed to be supported.

Michael - the changes are fine and identical to a patch that I have in 
my repo too. All I suggest is adding a comment to each ifdef so that 
readers know what is about. Also I would suggest intending in 
blockOrUnblock6 to make it easier to read.
