I think it is clear the solution is to map `port 0` to `port 10000 - 65000`. there are 2 potential todos here if we going down this path: 1. have a more randomized iterator just like you mentioned above, it could be put under `Netutils` that might be reused later. 2. with the randomized port iterator, do you think there's still need a hard timeout? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
