Load routes safely in SwaggerPlugin

[byamba-tumurkhuu]

I have a router that extends SimpleRouter:

class ApiRouter(controller: ApiController) extends SimpleRouter
{
  override def routes: Routes = {
    case GET(p"/") => controller.index
  }
}

And my routes file:

->         /                  ApiRouter

However when SwaggerPlugin loads the routes during the app initialization, it tries to load ApiRouter as a file thus throwing NullPointerException at the following code:

Source.fromInputStream(app.classloader.getResourceAsStream(routesFile)).mkString

This PR ignores any exceptions when loading routes and logs in debug level.

This isn't a viable solution.
You are just ignoring all this routes.

[byamba-tumurkhuu]

They're ignored because they can't be loaded. It's better to log if there is any problem during the loading, rather than killing the app with exception.

[MatteCarra]

Yes that's true.
I was hoping to find a better solution but it is impossible

Unfortunately I'm not getting any reviews.
