@JsonNaming strategy is not supported in GraalVM native image

[sarathchand09]

Overview

I am using Spring Boot 3.0 RC1 and GraalVM latest.

My native image works fine.

@JsonNaming(PropertyNamingStrategies.UpperSnakeCaseStrategy.class)

Using the above annotation for upper case JSON field names works fine with jar,
but it doesn't work when running in the native image.

I am also using Lombok @Data on my POJO.

What happens if you manually add GraalVM native image reflection configuration for com.fasterxml.jackson.databind.PropertyNamingStrategies.UpperSnakeCaseStrategy?

Note that we had a similar report in Spring Boot and we've just pushed something that would contribute those hints, see spring-projects/spring-boot#33080

Should be handled by #29646 fix.
