Injection of bean inside ClientHeadersFactory doesn't work

Question

I'm building a Quarkus app which handles http requests with resteasy and calls another api with restclient and I need to propagate a header and add another one on the fly so I added a class that implements ClientHeadersFactory.

Here's the code:

@ApplicationScoped
public abstract class MicroServicesHeaderHandler implements ClientHeadersFactory {

    @Inject
    MicroServicesConfig config;

    @Override
    public MultivaluedMap<String, String> update(MultivaluedMap<String, String> incomingHeaders,
                                                 MultivaluedMap<String, String> clientOutgoingHeaders) {

        // Will be merged with outgoing headers
        return new MultivaluedHashMap<>() {{
            put("Authorization", Collections.singletonList("Bearer " + config.getServices().get(getServiceName()).getAccessToken()));
            put("passport", Collections.singletonList(incomingHeaders.getFirst("passport")));
        }};
    }

    protected abstract String getServiceName();

My issue is that the injection of the config doesn't work. I tried both with @Inject and @Context, as mentioned in the javadoc of ClientHeadersFactory. I also tried to make the class non abstract but it doesn't change anything.

MicroServicesConfig is a @Startup bean because it needs to be initialized before Quarkus.run() is called, otherwise the hot reload doesn't work anymore, since it's required to handle requests. Here's the code FYI:

@Getter
@Startup
@ApplicationScoped
public final class MicroServicesConfig {
    
    private final Map<String, MicroService> services;

    MicroServicesConfig(AKV akv, ABS abs) {
                
        // some code to retrieve an encrypted file from a secure storage, decrypt it and initialize the map out of it
    }

It appears to be an issue with ClientHeadersFactory because if I inject my bean in my main class (@QuarkusMain), it works. I'm then able to assign the map to a public static map that I can then access from my HeaderHandler with Application.myPublicStaticMap but that's ugly so I would really prefer to avoid that.

I've searched online and saw several people having the same issue but according to this blogpost, or this one, it should work as of Quarkus 1.3 and MicroProfile 3.3 (RestClient 1.4) and I'm using Quarkus 1.5.2. Even the example in the second link doesn't work for me with the injection of UriInfo so the issue doesn't come from the bean I'm trying to inject.

I've been struggling with this for weeks and I'd really like to get rid of my workaround now. I'm probably just missing something but it's driving me crazy.

Thanks in advance for your help.
