Spring Boot 4 requires Jakarta EE 11. Jersey 4 will support EE 11 but
its release schedule is uncertain. Furthermore, Jersey does not yet
support Jackson 3 and there's no clear timeline for when Jackson 3
will be supported.
In light of the above, this commit removes support for Jersey.
Reinstating support can be considered once there's a Jersey GA that
supports Jakarta EE 11 or its clear that one will be available in
time for Boot's GA in November. Ideally, support for Jackson 3 would
also be available before reinstating Jersey support.
Closes gh-47017
Spring Framework 7.0 requires a Servlet 6.1 baseline for Servlet containers.
Partial Servlet 6.1 support is available on the `main` Undertow branch,
but there isn't any milestone version available for the undertow 2.4
generation. At this stage of our 4.0 schedule, we think it's safer to drop
Undertow support now.
Closes: gh-46917
Restore the `spring-boot-autoconfigure-classic` module, but add
a starter and an extra `spring-boot-autoconfigure-classic-modules`
POM in order to push the exclusions further away.
This should allow `spring-boot-starter-classic` to be combined
with other starters and hopefully have the expected dependencies
resolved.
