According to

http://bugs.sun.com/view_bug.do;jsessionid=70afcb213c8795d4c8b77a9d4175?bug_id=4527345

Sun has finally fixed this in "jdk7 build 36".
(Took them less than 7 years :-)

Here's the documentation on the source-specific join() method:

http://download.java.net/jdk7/docs/api/java/nio/channels/MulticastChannel.html#join(java.net.InetAddress,%20java.net.NetworkInterface,%20java.net.InetAddress)

JDK 7 snapshots are available here (build 39 is current):
