Hi guys!

The commit sha: 9c48756 (cc @iltar) changed some behavior in all versions of Symfony, I think on accident.

Consider the following:

/**
 * @Route("/product/{id}")
 */
public function showAction($id2)
{
}

Previously, this would have thrown the following error:

Controller "SomeController::showAction" requires that you provide a value for the "$id2" argument (because there is no default value or because there is a non optional argument after this one).

But after this commit, it does not throw the error, and instead $id2 is set to null in all cases. The specific problem is this block: 9c48756#diff-8518ab757bc9acd6d5a874a2e2737502R135

Was this expected? It's a step back in DX, as you can now silently mess up your route param without being notified.

Cheers!
