So if you pass a timeout that's largely lesser than that you will practically never see the `ConnectException`. It may still happen if the selector/poller thread is paused for too long, so it's good to cater for that.

That is, `connect(..., 5000)` threw `ConnectionException` in less than 1s, which is less than both the timeout I provide (i.e., 5s) and the OS defaults to. Am I missing something?

I was speaking about unix platforms behaviour here. The test excludes windows platforms.
