Jersey resources used the wrong injector

[Jackyjjc]

My app builds the guice bundle in the following way:

guiceBundle = GuiceBundle.defaultBuilder(DWConfiguration.class)
            .modules(appModule)
            .build();

The jersey resource is like this:

@Path("/")
@Produces(APPLICATION_JSON)
public class AppResource {
    private final KCL KCL;

    @Inject
    public AppResource(KCL KCL) {
        this.KCL = KCL;
    }
}

In the Guice module we have:

   @Override
    public void configure(Binder binder) {
        binder.bind(KCL.class);
        binder.bind(AppResource.class);
    }

This is the error I get

It looks to me that jersey was trying to use HK2 injector rather than the Guice one when trying to inject the KCL class. It seems to be related to https://github.com/HubSpot/dropwizard-guicier/issues/13 but I'm not 100% sure. I can "fix" this issue by calling

JerseyGuiceUtils.reset();

However i have no idea if this will make other things not work. Is there a proper way to fix this?

@Jackyjjc where did you do this call? JerseyGuiceUtils.reset();

[Jackyjjc]

@alexey-krylow sorry it has been a while since I submitted this issue. I don't remember where I made the call nor I still have the code. I believe I made the call in either dropwizard setup or run function.
