Based on my prototyping in JENKINS-73120, there is quite a bit of work to support Jetty 12 (even just EE 8 with javax imports), blocked on the requirement of Java 17. From my perspective the sooner we require Java 17, the better. Perhaps we can require Java 17 in weeklies two weeks earlier than planned, acknowledging that this creates two fewer choices for LTS selection. Thoughts?
