Yes, I agree that getNextPort doesn't really get the next free port, and
bind to port 0 is the right way.

But if I remembered clearly, in Jetty based tests thread, someone objected
automatically select port.

Repeatability.  IMO, there should be no random elements in our testing.
That leads to frustration, fear, despair, pathos, pain, agony, angst and
much pulling of limited resources, like hair, in my case."

Additionally, getNextPort() is referenced many times in LUNI, NIO modules.
Most of them are used to avoid port conflict. Shall we fix those codes?
