The generated AccessApi of the quarkus client does not work for the Quarkus REST Client because it magically drops the last slash from the path.

The generated AccessApi looks like:

@RegisterRestClient
@RegisterProvider(ApiExceptionMapper.class)
@Path("/access/")
public interface AccessApi {
    @GET
    @Produces({"application/json"})
    AccessPagination getPrincipalAccess(@QueryParam("application") String application, @QueryParam("username") String username, @HeaderParam("x-rh-identity") String xRhIdentity, @QueryParam("limit") @DefaultValue("10") Integer limit, @QueryParam("offset") @DefaultValue("0") Integer offset) throws ApiException, ProcessingException;
}

The problem is that the Quarkus REST Client extension is not respecting the value "/access/" from the "@Path" annotation.

This issue has been reported in Quarkus several times. Examples:

• https://github.com/quarkusio/quarkus/issues/41689
• https://github.com/quarkusio/quarkus/issues/27050

But since this is a behaviour that has been part of REST Client from a while, the Quarkus team is reluctant to change to avoid breaking changes. More context in https://github.com/quarkusio/quarkus/issues/41689.

As a workaround, we need to configure the OpenAPI generator to place the "@Path("/access/")" at method level.
