hey @tkuzynow, I changed the base-branch to have a better diff (to the one I already reviewed).
Just a question regarding src/test/java/de/caritas/cob/userservice/api/OrganizerIT.java there you added a Disabled

The rest looks fine.
Thanks,
Patric

why Disabled?

[tkuzynow]

Spring Boot 3.3.X introduced some refinements in Ahead-of-Time (AOT) processing, which affects how beans are detected and registered. The error was that AOT processing could not resolve a constructor for MongoClient, which was not even used explicitly in this test.

I investigated and spent quite some time on it, but could not find any working fix for this test in reasonable time.
This was clearly an issue with the test, and not the application.
Moreover this feature is not being used in our codebase (this is related to the old-way appointments were handled for caritas, so I decided to mark it as disabled to proceed with more important tests on the cluster).

To be more specific:
The test itself works (from IDE), but the process-aot maven phase was throwing the exception. This was executed only when you run mvn install.

hey @tkuzynow, looks fine what I can see.
