On WSL with Ubuntu 16.04.6 LTS method getNextAvailable iterates all ports and then crashes JVM (logs in attachments).
This can be reproduced by running AvailablePortFinderTest on one of these platforms.
We can take a look to other implementations, if they performs better and are usable on all supported OS.
//Edit: Removed W10 from environments, as I cannot reproduce it again. On WSL it is reproducible always.
