Having this in config:

'di' => array(
    'instance' => array(
        'alias' => array(
            'Session' => 'Zend\Session\Container',
        ,
    ),
),

And running $this->locator->get('Session') gives exception:

1) An abstract factory could not create an instance of session(alias: Session). 2) An exception was raised while creating "Session"; no instance returned 3)

Zend\Session\Exception\InvalidArgumentException

Seems it tries to contruct object with null params even they are all optional.

Expected behaviour same as if I put this into the config:

'service_manager' => array(
    'invokables' => array(
        'Session' => 'Zend\Session\Container',
    ),
),
