Fix Version/s: 4.0.0
Resolution: Duplicate
> Support for Jakarta EE 9.x to allow applications to migrate
> -----------------------------------------------------------
>
> Key: KAFKA-13027
> URL: https://issues.apache.org/jira/browse/KAFKA-13027
> Project: Kafka
> Issue Type: Improvement
> Affects Versions: 2.8.0
> Reporter: Frode Carlsen
> Priority: Major
> Fix For: 4.0.0
>
>
> Some of the kafka libraries (such as connect-api) have direct dependencies on
> older Java EE 8 specifications (e.g. javax.ws.rs:javax.ws.rs-api:2.1.1).
> This creates issues in environments upgrading to Jakarta 9.0 and beyond (9.1
> requires minimum Java 11). For example upgrading web application servers
> such as migrating to Jetty 11.
> The main thing preventing backwards compatibility is that the package
> namespace has moved from "*javax.**" to "*jakarta.**", along with a few
> namespace changes in XML configuration files. (new specifications are
> published here [https://jakarta.ee/specifications/,] along with references to
> official artifacts and compliant implementations).
> From KAFKA-12894 (KIP-705) it appears dropping support for java 8 won't
> happen till Q4 2022, which makes it harder to migrate to Jakarta 9.1, but 9.0
> is still Java 8 compatible.
> Therefore, to allow projects that use Kafka client libraries to migrate prior
> to the full work being completed in a future Kafka version, would it be
> possible to generate Jakarta 9 compatible artifacts and dual publish these
> for libraries that now depend on javax.ws.rs / javax.servlet and similar?
> This is done by a number of open source libraries, as an alternative to
> having different release branches for the time being. Other than the
> namespace change in 9.0 and minimum java LTS version in 9.1, the apis are
> fully compatible with Java EE 8.
> As a suggestion, this fairly easy to do automaticallly using the
> [https://github.com/eclipse/transformer/] for migration (most projects end up
> publishing under artifacts with a either "-jakarta" as a suffix on the
> artifactId or classifier)
