Dependency quarkus-micrometer-registry-prometheus removes @Path annotation from a class

[interphase404]

Describe the bug

If dependency quarkus-micrometer-registry-prometheus is present, @Path annotation disappears from resource classes in runtime. For example it completely removes the possibility of calling method path(Class resource) from jakarta.ws.rs.core.UriBuilder because the class is required to be annotated with @Path and runtime doesn't have this information

Expected behavior

@Path annotation should be present when calling getClass().getAnnotations()

Actual behavior

@Path annotation is not present when calling getClass().getAnnotations()

How to Reproduce?

It is very simple to reproduce this issue.

1. Create application using: quarkus create app --extension='resteasy-jackson'
2. Add dependency quarkus-micrometer-registry-prometheus
3. Attach debugger to created hello() method
4. Call endpoint http://localhost:8080/hello
5. Execute code in the debugger getClass().getAnnotations()

Not sure if I understand the problem, @interphase404 can you please add a reproducer?

[interphase404]

I'm really sorry for not being able to describe this issue more clearly. Here is a reproducer: https://github.com/interphase404/quarkus-reproducer-38010

If you run it using: mvn quarkus:dev and call endpoint http://localhost:8080/annotations only this will be printed to the console: 2024-01-03 20:45:48,468 INFO [org.acm.AnnotationResource] (executor-thread-1) @jakarta.enterprise.context.ApplicationScoped()

However if you remove the dependncy quarkus-micrometer-registry-prometheus, then the console will display this: 2024-01-03 20:47:27,170 INFO [org.acm.AnnotationResource] (executor-thread-1) @jakarta.ws.rs.Path(value="/annotations") 2024-01-03 20:47:27,173 INFO [org.acm.AnnotationResource] (executor-thread-1) @jakarta.enterprise.context.ApplicationScoped()

Got it! Sounds like a bug indeed.

This only happens with RESTEasy Classic (RESTeasy Reactive is not affected). The high level reason it happens is because the JAX-RS Resource class is scoped as @ApplicationScoped - why this happens I do not know.
