This is related to the multicast deprecation changes.

The tests pass on Java 17 but fail on Java 11.

I'm investigating...

Oh that is just pure genius. The behaviour of IP_MULTICAST_LOOP is 
inverted for Java 14+.

I cannot believe that this change has not be back-ported to Java 11 and 
Java 8. Well actually, I can. I suspect it wasn't back-ported due to 
fear of breakage.

This looks like a job for JreCompat.

Sigh.
