8207404: MulticastSocket tests failing on Aix

[Lindenmaier, Goetz]

i Steve, 

thanks for looking at this issue.

> Should these tests work without having IPV6 configured on the interface?
In general, tests should not show errors if a system does not meet
the requirements for the test. In such cases the test should 
be skipped somehow. Maybe only a test fix is needed.

Can you check on a non-aix machine without ipv6 whether the test
passes?

This is our test machine:

bash-4.3$ ifconfig -a
en0: flags=1e084863,480<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),CHAIN>
        inet 10.xx.xxx.xxx netmask 0xfffffe00 broadcast 10.xx.xxx.xxx
         tcp_sendspace 262144 tcp_recvspace 262144 rfc1323 1
lo0: flags=e08084b,c0<UP,BROADCAST,LOOPBACK,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,LARGESEND,CHAIN>
        inet 127.x.x.x netmask 0xff000000 broadcast 127.xxx.xxx.xxx
        inet6 ::1%1/0
         tcp_sendspace 131072 tcp_recvspace 131072 rfc1323 1

I think this message should be posted to core-libs-dev, too. That's also
the list where a potential fix needs to be reviewed.

Best regards,
  Goetz.
