This kind of behavior would happen to me on Mac OS X El Capitan using Jetty 9.3.15.v20161220. It was easy to reproduce:
1. Make my cell phone a WIFI hotspot 2. Disable cellular data, thus making the hotspot a deadend 3. Connect my Mac to the hotspot 4. Start embedded Jetty It would hang when log4j was being initialized and actually had nothing to do with Jetty. It would hang here: InetAddress addr = InetAddress.getLocalHost() in NetUtils. I fixed it by adding my laptop's hostname and localhost to /etc/hosts as 127.0.0.1 and ::1. See [1] I know that it is somewhat different situation, but I'm wondering if the root cause is the same -- slow DNS resolution in Java's InetAddress. HTH!
