--- Comment #2 from Craig Rodrigues <rodrigc at FreeBSD.org> ---
I did some more analysis and found that this code:


 13253 java     CALL  bind(0x4,0x7fffffbfd7a8,0x1c)
 13253 java     STRU  struct sockaddr { AF_INET6, [::]:33848 }
 13253 java     RET   bind 0
 13253 java     CALL  setsockopt(0x4,0x29,0x9,0x7fffffbfd7f4,0x4)
 13253 java     RET   setsockopt 0
 13253 java     CALL  getsockopt(0x4,0x29,0x9,0x7fffffbfd8ac,0x7fffffbfd864)
 13253 java     RET   getsockopt 0
 13253 java     CALL  setsockopt(0x4,0x29,0xc,0x7fffffbfd8c0,0x14)
 13253 java     RET   setsockopt -1 errno 22 Invalid argument

is happening inside the mcast_join_leave() function inside the JDK here:

http://hg.openjdk.java.net/jdk7/jdk7/jdk/file/9b8c96f96a0f/src/solaris/native/java/net/PlainDatagramSocketImpl.c

>From looking at the FreeBSD header files,
IPPROTO_IPV6 = 41 (0x29)
IPV6_MULTICAST_IF = 
IPV6_JOIN_GROUP = 12 (0xc)_

inside the mcast_join_leave() function what is basically happening is:

setsockopt(0x4, IPPROTO_IPV6, IPV6_MULTICAST_IF, ...)
getsockopt(0x4, IPPROTO_IPV6, IPV6_MULTICAST_IF, ...)
setsockopt(0x4, IPPROTO_IPV6, IPV6_JOIN_GROUP, ...)

the second setsockopt() is returning EINVAL
