Server doesn't bind to IP4 requested socket number, but works in IP6

I have a Java program that opens a ServerSocket.
netstat -tlpn shows that if I open port 20 (for example):

-- IP6 binds a TCP socket to :::20
-- IP4 binds a TCP socket 127.0.0.1:32000

This doesn't necessarily work right. Some clients can connect, others cannot.

This seems to have broken between fc22 and fc24.

I disabled selinux, to no effect. The process is running as root. I put it in a systemd unit file, which worked under the previous fc22 host.

What would cause binding to be mucked up that way?
