Carsten Ziegeler commented on FELIX-6701:
-----------------------------------------
So far we managed to have an implementation that support various servlet API
versions; right now we basically support servlet 2 to 6 with both the
http.jetty and the http.jetty12 implementation - there are some problems if
some of the deprecated methods are used which got removed in the servlet API 6.
But other than that you can run servlet 3 or servlet 5 code on http.jetty12.
We only have http.jetty and http.jetty12 because of the Java 17 requirement for
Jetty12 - eventually we can put http.jetty to maintenance.
Therefore we should see that http.jetty12 just uses the latest available jetty
implementation and with that we would support Jakarta EE11;
We might break code that uses Jetty classes directly as we move along to newer
Jetty versions, but that seems to be unavoidable.

> Key: FELIX-6701
> URL: https://issues.apache.org/jira/browse/FELIX-6701
> Project: Felix
> Issue Type: Improvement
> Components: HTTP Service
> Reporter: Paul Rütter
> Priority: Major
>
> Jakarta EE 11 should be released within a couple of months, thus Jetty will
> follow with a 12.1.x ([https://webtide.com/introducing-jetty-12/).
> |https://webtide.com/introducing-jetty-12/).]Ideally, this will become a new
> feature of the Jetty12 bundle.
> What are the ideas to support this?
> For the light bundle, i can imagine that the EE11 classes can be detected in
> the classloader, like is done for websocket support. For the main jar, would
> both EE10 and EE11 servlet classes be part of it? Or would we introduce new
> classifiers for EE11 servlet? Probably, a new configuration option is needed
> to specify the EE version to run.
> These imports would be problematic if the EE10 classes are not available,
> [https://github.com/apache/felix-dev/blob/517f9a0c89cad1866f315255568b40c568f5239d/http/jetty12/src/main/java/org/apache/felix/http/jetty/internal/JettyService.java#L34.]

> Just wondering how new (or existing 8/9, for that matter) EE specifications
> would be part of the jetty12 bundle. Of course, we could already try it out
> with EE9 as an exercise to ease transition to Jetty12.
