Start with jdk/test/sun/rmi/transport/tcp/DisableRMIOverHttp/DisableRMIOverHTTPTest.java, especially the call at line 88 and HttpOutFactory at line 126. Re-run DisableRMIOverHTTPTest on the affected macOS 10.13 hosts and inspect the RMI-through-HTTP failure. Done means the test no longer fails with Connection refused on both listed hosts.
