Restore Jolokia support now that it is compatible with Jakarta EE 9+

[tadayosi]

The Jolokia endpoint was dropped from Spring Boot 3 because it didn't yet support Servlet API 5+ #28704.

Now the Jolokia project is working on 2.0 release, which aims at supporting Jakarta EE 9+ including Servlet API 5 jolokia/jolokia#568. It would be great if you could restore the Jolokia endpoint for Spring Boot 3 once the version is released.

Thanks.

Thanks, but we don't need an issue for this as it'll just sit blocked indefinitely. We're already keeping an eye on the Jolokia project's progress (by watching jolokia/jolokia#451 for example). As and when there's a release available, or even a date planned for such a release, we'll look more closely at possibly restoring support for Jolokia.

Looking more closely at Jolokia 2.x, the project now provides its own auto-configuration. Thanks to the Jolokia team's efforts, this means that there's nothing left for us to do here. As Jolokia now depends on Spring Boot we avoid referring to it from our published artifacts to avoid a circular dependency between the two projects.
