I found a strand behavior with servicecontainer and autowire.

When I inject a service container and autowire it, the parameter bag is not resolved.

Basicly, with this definition of my service

    widget.manager:
        class: Widgets\Bundle\CoreBundle\Manager\WidgetManager
        arguments: ['@widget.renderer', '@service_container']

I am able to get parameters like:

$this->serviceContainer->getParameter('my.param')

But when I use autowire like this

    widget.manager:
        class: Widgets\Bundle\CoreBundle\Manager\WidgetManager
        autowire: true

on the same service, the parameter bag is not resolved and i get an error like "the prameter 'my parameter' does not exist".

Maybe it's a normal behavior, cause the service container is a special service, but we should have at least some meaningfull error.
