Unsupported socket address: ''

We use Jenkins to build our project with Kubernetes agents, so a brand new agent container is created for every build.
Without any notable changes, we ran into the following issue:

The build failed.
Restarting the build (with another brand new agent container) "fixed" the issue.

No clue what the cause was. There were zero changes to our code, or the build environment.

Cannot reproduce.
But wanted to post it anyway in case this isn't 1:10000 edge-case, and others might find a reproduction scenario.

Not sure in what case https://github.com/apache/maven-mvnd/blob/master/common/src/main/java/org/mvndaemon/mvnd/common/DaemonInfo.java#L87 DaemonInfo.getAddress() might return an empty String, but apparently it's possible.
