I think the main thing is that I suspect you'll need to exclude more tests as there are several tests for DatagramChannel that join multicast groups and some of these likely assume they can join an IPv4 multicast group when cases where the DatagramChannel is created with the no-arg open method (and IPv6 is enabled) or with the IPV6 protocol family.

I've created https://bugs.openjdk.org/browse/JDK-8313404 to extract the fix for jdk_foreign from this PR. It's cleaner, also for backporting, although it incurs some process overhead.
