Using deprecated '-debug' fallback for parameter name resolution

[sergey-morenets]

Hi

We've migrated from Spring Boot 2.7.x to Spring Boot 3.0.5 and observed a lot of warning messages in the console:

22:38:33.661 WARN - Using deprecated '-debug' fallback for parameter name resolution. Compile the affected code with '-parameters' instead or avoid its introspection: demo.UserRepository

This warning is printed for some Spring Data repository interfaces (but not for all). It seems this issue was already fixed in Spring 6.0.4 - spring-projects/spring-framework#29612

We're using Spring 6.0.7 now but issue still reproduces.

The warning itself is a valid one, or are you using -parameters as instructed by the warning?

Hi

@schauder

Thank you for the quick response. No, I don't use any Spring Boot or JVM arguments.

If you are using Spring Boot you shouldn't need any special configuration.
If you are using Spring Boot please provide a reproducer.

Without Spring Boot you need to use that flag.

Hi @vishalsingh2972

Unfortunately I have no solution. I see this warning even if run my application using Spring Boot plugin.

If the problem persists I recommend creating a reproducer and filing an issue against Spring Framework or Spring Boot
