OK, looks better, more explicit so that we can find out why this is failing.
There's still a subtle issue in the reporting though. Consider if on attempt N
the ServerSocket call gets a valid port but it's one of the reserved ports.
Then, unusedRandomPort will be >= 0 and isReservedPort() will be true, so we'll
get the "INFO" message.
Now on attempt N+1 suppose ServerSocket throws an exception. We'll get the
exception stack trace, but then unusedRandomPort will still have its previous
value, and we'll get the INFO message again, but spuriously this time. I hate
to ask you to update this again, but as it stands I think the output will be
I think setting unusedRandomPort back to -1 at the top of the loop should fix it.
You need me to push this for you? I can drop in this change before I push, if
you're OK with me doing this.
