Microprofile REST Client entry point

[danilopiazza]

I was having a hard time while debugging an issue with an injected @RestClient, and I wondered: which class is the entry point of a Quarkus REST Client?

In other words, given this interface:

@Path("/extensions")
@RegisterRestClient
public interface ExtensionsService {
    @GET
    Set<Extension> getById(@QueryParam("id") String id);
}

and this caller:

@RestClient 
ExtensionsService extensionsService;

...

extensionsService.getById(id);

where should I put a breakpoint to step through the Quarkus and/or RESTEasy implementation of the ExtensionService interface?

My original issue (not relevant to this question)

The issue, now solved, which led me to asking this question, was caused by my client using the wrong multipart encoder. It was similar to #39751.

There is admittedly a lot of code that is generated for the REST client, but debugging ClientRequestSendHandler (or something like that, I'm writing without access to a computer now) is usually a good starting point

Thank you! ClientSendRequestHandler. I'll start from there!
