Spring Boot 4 and Jackson 3 Alignment Issue

[hantsy]

Spring 7 and Spring Boot 4 have switched to use Jackson 3, but this project still use the legay Jackson 2.

Some APIs such as ProblemExceptionHandler(final ObjectMapper mapper, final HttpAdviceTrait advice) is not compatible.

This is a completly broken change , how do we get this fixed?

I would like to highlight that since spring framework 6 - there's native implementation of problem type: https://docs.spring.io/spring-framework/reference/web/webmvc/mvc-ann-rest-exceptions.html

Response content type controlled via following property:
https://docs.spring.io/spring-boot/appendix/application-properties/index.html#application-properties.web.spring.mvc.problemdetails.enabled

Showcase project of Spring Problem type: https://github.com/fatroom/problem-demo

@fatroom I know well about the problem details brought in Spring 6, but it lacked some features that included in Zalando/Problem, eg. Validation errors, this is easy to write a custom exception handler, another is the security errors, Zalando/Problem has a good integration for it, and convert all security errors to the Problem standard format.
