> Many of the unit tests in Jenkins fail because of the use of {{`InetAddress.getLocalHost()`}} in the test classes.
> The Jenkins agents needs a public ipaddress (and a hostname associated to it) so the Jenkins master can connect to them (agents can be hosted externally, by donating third-parties).
> The call to {{`InetAddress.getLocalHost()`}} then resolves this public hostname.
> This is not listed in {{`/etc/hosts`}}, and we don't want it to be either (in case of accidental external port opening). (This is also ASF policy on this infrastructure.)
> The unit test code needs to replace these code occurrences with the call to {{`FBUtilities.getLocalAddress()`}}
