Access HttpServletRequest from an Authenticator using Dropwizard

Using DropWizard(Jersey Server), Is it possible to access HttpServletRequest from an Authenticator?

I would give it an attribute.

I tried with:

@Context
private HttpServletRequest servletRequest;

But it's not injected.

I registered my Authenticator using:

env.jersey().register(
                new AuthDynamicFeature(new BasicCredentialAuthFilter.Builder<User>().setAuthenticator(new FooAuthentificator())
                        .setRealm("Realm").buildAuthFilter()));
