Description

Keycloak software from the Java ecosystem currently uses Jackson2 as baseline for JSON serde.
Jackson now provides major version 3.
Spring Boot 4 now uses Jackson3 under the hood, for Quarkus I cannot tell.

In order to keep wide range adoption, I think it would be very beneficial to have the Keycloak client also use Jackson 3.

No response

Motivation

I am currently evaluating the upgrade path to Spring Boot 4 in one of our services.
Everything when smooth so far, yet the I am fighting Jackson dependencies.
There is a Jackson2 compatibility mode in Spring Boot 4, but it does not feel right to use it in a modern ecosystem. It also might get removed in the future.

Details

No further details necessary IMHO.
