Spring 6.0.1 and newer requires/prefers compilation with "-parameters"

When starting an application with Spring 6.0.2, Spring Batch 5.0.0 and Spring Boot 3.0.0, Spring logs 86 warning messages that look like this:

12:58:39.789 [main] WARN  o.s.c.LocalVariableTableParameterNameDiscoverer - Using deprecated '-debug' fallback for parameter name resolution. Compile the affected code with '-parameters' instead or avoid its introspection: org.springframework.batch.integration.launch.JobLaunchingMessageHandler

LocalVariableTableParameterNameDiscoverer is marked as deprecated for removal. This means that it might be removed in Spring 6.1.

I got several similar warning messages related to my own code as well, these went away when adding the -parameters flag in my maven-compiler-plugin configuration. Only the messages related to Spring Batch remain.

To resolve this, could you add the -parameters flag to your build for a later release?

Thank you for raising this! I will plan it for v5.0.1.
