Update Jetty and Javalin versions #234
Description
Due to Security alert caused by jetty v9:
- Update Jetty to version
>=10which is available via the current (and newest) Eclipse release- Remark: Since 2021-06 Jetty v10 is available, but it caused issues (see also #125, #123, #117 Fix dependencies, reuse TransactionChangeRecorder and use generic stand-in for contributors/developers #124). Please investigate what are the problems and how we can overcome them.
- This means we can remove the (rather instalbe) jetty update site
- Hence update to Eclipse release
2022-12 - Update Javalin to version 5
With 2022-06 Jetty 9 was completeley removed from the Eclipse release and Javalin 5 also switched to Jetty 10, so we should conclude this switch also soon.
