Support Spring 6 and Spring Boot 3
The current version does not seem to do anything when added to a Spring Boot 3.0.0-M3 application. Will have to investigate what changed exactly and why things do not seem to be working.
See this section in Preparing for Spring Boot 3.0.
Main issue should be the use of Jakarta EE 9 APIs (jakarta.) instead of EE 8 (javax.), e.g. javax.validation.ConstraintViolation should be jakarta.validation.ConstraintViolation.
Tried Spring Boot 3 with the current release and it fails to launch as the javax.* is not (and should not be) in the classpath:

Thank you for your input @manosbatsis . if you want to use this library with Spring Boot 3 (milestones), you can use the version on the branch feature/spring-6-boot-3.
Kudos and thank you @wimdeblauwe. Out of curiosity (and the many libs with similar issues out there):
- When do intent to release this?
- Will you stop support for Spring Boot 2 or maintain two artifacts/classifiers/variants?
Not sure how easy adapters or other refactoring could allow for a base module and separate modules/artifacts on top, while Gradle variants or Maven classifiers don't seem relevant here either :-/
My idea was to keep this branch up to date with each milestone of Spring (Boot) and release when they release. The version of this lib that is compatible with SB 3 would be version 4.x. I would keep version 3.x for compatibility with SB 2.
Can I ask how would RFC 7807 to be supported Spring 6 affects this? Since RFC 7807 is about defining the standard API error response, which is the goal of this library to provide consistent error message.
See https://github.com/wimdeblauwe/error-handling-spring-boot-starter/issues/59 for the discussion on RFC 7807
