javalin: Can't bind to port - always reports it's 7000

Actual behavior (the bug) When Javalin (Jetty) tries to bind to a port that’s in use, it will always complain that it’s port 7000 whatever port it’s binding to.

Expected behavior If it’s trying to bind to port 443, then the error message should say that.

To Reproduce Start up 2 Javalin server on the same port.

Additional context Example stack trace (notice the IOException part):

java.lang.RuntimeException: Port already in use. Make sure no other process is using port 7000 and try again.
