Custom User-Agent header ignored

[luca-vercelli]

Describe the bug

We have a reactive rest client where we set a custom User-Agent header via the @ClientHeaderParam annotation.
However this is ignored and replaced with "Resteasy Reactive Client".

This does not happen with legacy resteasy client.

See also issue #23966. In that issue a workaround is described (using a ClientHeadersFactory).

Expected behavior

The HTTP call should include the header User-Agent: my-custom-header

Actual behavior

The HTTP call includes the header User-Agent: Resteasy Reactive Client

How to Reproduce?

You need any rest client

@Path("/somepath")
@ClientHeaderParam(name = "User-Agent", value = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.95 Safari/537.11") 
@RegisterRestClient
public interface MyApi {

  @GET
  Response somepath();

}

and call it via

@Inject
@RestClient
MyApi  api;

....
api.somepath()
