Native image tests works fine with 3.0.5 but fails with 3.1.0

The tests fail with:

Hi @phejl,

That's unfortunately insufficient information for us to diagnose the issue.

Please provide a minimal sample that reproduces the issue, preferably something that we can download and run (for example, a ZIP file or a public Git repository).

Thanks

[phejl]

@sbrannen Thank you. Yeah sure I'll try. I'm not done with that one yet :) Hopefully I'll get some clue. Proxies seem to be generated.

[phejl]

@sbrannen Hm, afterall the underlying issue is this: #30525 (comment)

When org.springframework.boot.test.autoconfigure.web.servlet.SpringBootMockMvcBuilderCustomizer is registered for reflection the tests pass ok.

[sbrannen]

Thanks for the feedback.

In light of that, I am closing this issue.
