Description

The YarnTestBase contains allow-list items like this:

Remote connection to \\[null\\] failed with java.net.ConnectException: Connection refused

I've seen this exception a few times without the address being null. This could be due to difference in how Java 17 resolves addresses .
In any case I don't see any harm in relaxing this regex to accept any address.
