path parameterin request.params is not accessible in before filter

[M-Razavi]

I want to check all parameters in a before filter for XSS attack and escape them, but param size is 0 in before filter until mail request.

Yes, I've observed this in 2.8.0. Given:

public static void main(String[] args) {
    Service spark = Service.ignite();

    spark.get("/foobar/:id", (request, response) -> {
        System.out.println("get: " + request.params("id"));
        return null;
    });

    spark.before((request, response) -> System.out.println("before: " + request.params("id")));

    spark.after((request, response) -> System.out.println("after: " + request.params("id")));

    spark.afterAfter((request, response) -> System.out.println("afterAfter: " + request.params("id")));

    spark.awaitInitialization();
}

when issuing:

$ curl http://localhost:4567/foobar/123456

the following is printed to stdout:

before: null
get: 123456
after: null
afterAfter: null

So they are not available in any filter. I'm guessing this might not be an easy issue to fix?

The route hasn't been matched yet, so the before filter can't know what the params are.
