Maybe use @AutoService instead ?

[murdos]

I'm not sure adding yet another dependency and another annotation processor is worth the value here, for something that is supposed to be a temporary workaround.

Adding a file that will need to be cleaned up later doesn't seem better.

[murdos]

Does really cleaning one file (JHipsterBlockHoundIntegration.java) or two files (JHipsterBlockHoundIntegration.java + meta-inf service declaration) makes a difference?

On the other hand, we have to deal with adding a new dependency (com.google.auto.service:auto-service-annotations), a new annotation processor (com.google.auto.service:auto-service) and a new property for the version that will have to be updated from time to time, for 2 build systems (gradle and maven).

I'm really not convinced here, in this context, with the use of @Autoservice, but I can add it others think it's the better solution.
@jhipster/developers what do you think?

Tests pass - ship it! 🚢

LGTM. Feel free to merge @murdos

@murdos webflux started failing with this PR.

Suddenly webflux tests started failing at #13021 with a minor change and I had now clue why.
MariaDB just timeout without no useful error.
Changing sqfull from MariaDB to postgres shows the error.

Merged #13031 to confirm.
