Jersey Async ContainerRequestFilter

I have a Jersey REST API and am using a ContainerRequestFilter to handle authorization. I'm also using @ManagedAsync on all endpoints so that my API can serve thousands of concurrent requests.

My authorization filter hits a remote service, but when the filter is run, Jersey hasn't yet added the current thread to it's internal ExecutorService, so I'm completely losing the async benefits.

Can I tell Jersey that I want this ContainerRequestFilter to be asynchronous?

@Priority(Priorities.AUTHORIZATION)
public class AuthorizationFilter implements ContainerRequestFilter
{
    @Inject
    private AuthorizationService authSvc;

    @Override
    public void filter(ContainerRequestContext requestContext) throws IOException
    {
        String authToken = requestContext.getHeaderString(HttpHeaders.AUTHORIZATION);

        // HITS A REMOTE SERVER
        AuthorizationResponse authResponse = authSvc.authorize(authToken);

        if (!authResponse.isAuthorized())
        {
            requestContext.abortWith(Response.status(Response.Status.UNAUTHORIZED)
                    .entity("unauthorized!")
                    .build());
        }
    }
}

And here's an example resource:

@Path("/stuff")
@Produces(MediaType.APPLICATION_JSON)
public class StuffResource
{
    @GET
    @Path("/{id}")
    @ManagedAsync
    public void getById(@PathParam("id") long id, @Suspended final AsyncResponse ar)
    {
        Stuff s;

        // HIT THE DATABASE FOR STUFF

        ar.resume(s);
    }
}

UPDATE Just heard back from the Jersey guys, and this is not possible as of 2.7. Only the resource method itself is invoked asynchronously, not filters. Any suggestions for proceeding still welcome.
