On openjdk25 (current stable java), the code at the top works whatever the
net.inet6.ip6.v6only sysctl is set to.
But, with -Djava.net.preferIPv4Stack=3Dtrue the code fails with "Failed to
connect to localhost with INET6"
The code works if you dont define java.net.preferIPv4Stack or set it to fal=
se.
I think it should work regardless of what you set the value to, it does in
linux. However, the current state is better than what it was in openjdk17. =
So I
think you can close this issue.
