Hi All,

I have been having a look at this issue:  https://bugs.openjdk.java.net/browse/JDK-8207404
which was raised by  Goetz Lindenmaier.

When I ran the tests on my AIX system I got the same results as Goetz listed in the issue.

Looking at the failure I noticed that it was failing on a setsockopt call in the native code in
the PlainDatagramSocketImpl.c file which returned a EADDRNOTAVAIL (Can't assign requested address)

Looking at my network configuration using "ifconfig -a", I noticed that my interface "en0" which the test
was trying to use did not have an inet6 address configured (see below - some addresses have been obfuscated with x's).

en0: flags=1e084863,14c0<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),LARGESEND,CHAIN>
        inet 9.20.xx.xx netmask 0xffffff00 broadcast 9.20.xx.xxx
         tcp_sendspace 262144 tcp_recvspace 262144 rfc1323 1

configuring the IPV6 on my AIX box I then had a inet6 address configured for en0

en0: flags=1e084863,14c0<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),LARGESEND,CHAIN>
        inet 9.20.xx.xx netmask 0xffffff00 broadcast 9.20.xx.xxx
        inet6 fe80::xxxx:xxxx:xxxx:xxxx/64
         tcp_sendspace 262144 tcp_recvspace 262144 rfc1323 1

with this configured the MulticastSocket tests all passed.

Should these tests work without having IPV6 configured on the interface?

Goetz, do you have IPV6 configured on the machine you were running these tests on?

Thanks
