Spring Framework BeanPostProcessorChecker: warning logs about BeanPostProcessors

The context Spring Framework's BeanPostProcessorChecker has started to complain loudly (logs at WARN level) about the BeanPostProcessors in this repo.

Creating a Spring Boot application that hosts a gRPC server and uses multiple gRPC client stubs to access services. Spring Boot version: 3.3.2

Both client and server auto-configurations classes trigger the checker. The bug
