@eolivelli @hanm Now, an entirely different approach. Solving 2 issues at
the same time:
1) Close selector in shutdown() when Accept and Select thread haven't been
started yet. This will keep the original behaviour of eagerly register the
selector in the constructor and addresses your concerns.
2) Turned out that we have a similar issue in reconfig: There was an issue
with `ReconfigTest.testPortChangeToBlockedPort`: it expects the original port
to be released even if the new port cannot be bound. Sounds like a reasonable
expectation and the exception handler in the `reconfigure()` method confirms
this. Hence I fixed the code, not the test.
