There was a problem hiding this comment. What if this port isn't free? It's dangerous to make assumptions about whether a particular ports is free, especially since this can cause problems in Jenkins, where we might have multiple builds running concurrently on the same machine that are contending for ports. Could we use There was a problem hiding this comment. Hey, note There was a problem hiding this comment. Ah, I see. Thanks for explaining. |

It looks like we used to bind Jetty to a specific hostname / interface, but it doesn't look like the new code uses
