Running port() returning 0 if called to quickly

When trying to get the port spark is actually listening on with the port being set to 0, it can return 0 if called too quickly.
This seams to be because the server is initializing in a separate thread and therefor not setting the port number to the actual port number before calling port().
See example
public int initWeb() {
port(0);
get("/thing", (req, res) -> ...);
return port(); // returns 0
}
There also seams to be no way to check for the server being fully initialized as far as I can tell, but I could be wrong about that.

Try:
Spark.awaitInitialization();
