Missing native-image reflection hint for `org.springframework.data.domain.Unpaged`

[mmoayyed]

Environment

• Spring Data 3.2.2
• Spring Boot 3.2.1
• GraalVM 21.0.1+12.1 (build 21.0.1+12-jvmci-23.1-b19)

Problem

It appears that org.springframework.data.domain.Unpaged needs a few native-image hints:

Caused by: java.lang.ExceptionInInitializerError: null

I suspect this is new in 3.2.2 as I think 3.2.1 did OK in this area.

Link to GitHub Actions job that showcases the failure.
