I think the difference is in setMulticastInterface() in
PlainDatagramSocketImpl.c
#ifdef __linux__
mcast_set_if_by_if_v4(env, this, fd, value);
if (ipv6_available()) {
if ((*env)->ExceptionCheck(env)){
(*env)->ExceptionClear(env);
}
mcast_set_if_by_if_v6(env, this, fd, value);
}
#else /* __linux__ not defined */
if (ipv6_available()) {
mcast_set_if_by_if_v6(env, this, fd, value);
} else {
mcast_set_if_by_if_v4(env, this, fd, value);
}
#endif /* __linux__ */
We should probably follow the Linux way for AIX as well.
