8207404: MulticastSocket tests failing on Aix

[Steve Groeger]

Hi Chris / Volker,

I had already tried doing the same as is done for Linux, ie calling this 
first 

mcast_set_if_by_if_v4(env, this, fd, value);

This still fails for some reason with EADDRNOTAVAIL. 
This error gets cleared by the 

if ((*env)->ExceptionCheck(env)){
    (*env)->ExceptionClear(env);
}

as ipv6_available() still returns true, but we then still try and call 

mcast_set_if_by_if_v6(env, this, fd, value);

which again fails with EADDRNOTAVAIL. So we have the same result.

Thanks

I agree.
