springdoc-openapi-starter-webmvc-ui 3 : Upgrade Jackson 2 => Jackson 3 With Spring boot 4

[raymond10]

Hello,

After a migration of spring boot 3 to Spring boot 4 and to springdoc-openapi-starter-webmvc-ui 3.0.1,
I have an exception when I start my application.
With spring boot 4, I use now jackson 3, but springdoc-openapi-starter-webmvc-ui still use jackson 2.

Here is the detail of my exception :

::  :: 
:: Built with Spring Boot :: 4.0.1

org.springframework.context.ApplicationContextException: Unable to start web server

org.springframework.beans.factory.BeanCreationException: Error creating bean with name
