Quarkus: DeadLock when using CacheResult with Spring Data

[dubilyer]

Describe the bug
When using CacheResult annotation on method performing several calls to SpringData repository the program is stuck.

Expected behavior
Everything works smoothly

Actual behavior
All threads are in Waiting state (dump)

To Reproduce
Steps to reproduce the behavior:

1. Create a project with Spring Data repository (extends CrudRepository)
2. Create a method in another class, performing several calls (findById).
3. Annotate it with CacheResult

Thanks for reporting this.

I was not able to reproduce the problem unfortunately. Would you be able to supply a minimal reproducer containing only the Spring Data JPA and cache stuff that exhibits the problematic behavior?

[dubilyer]

I will try.

This probably shares the same root cause than #13158.

There's a good chance this issue was fixed with #13244.

Feel free to reopen if that's not the case.
