A micro Java library that does one thing and one thing only: finds a free local port (mainly) for testing purposes.

Finding a free local port is as easy as:

```

int port = FreePortFinder.findFreeLocalPort();

```

Which can then be used to set up local Jetty without hitting

```

java.net.BindException: Address already in use

```
