[PHP-BUG] Bug #71248 [NEW]: Wrong interface is enforced

From:             norbert at linuxnetworks dot de

Bug description:Wrong interface is enforced

Description:
------------
I ran into a weired problem with interfaces in combination with
namespaces. In the Aimeos library, decorators can be wrapped around
provider objects. The provider objects use this constructor signature:

public function __construct( \Aimeos\MShop\Context\Item\Iface $context,
\Aimeos\MShop\Service\Item\Iface $serviceItem );

Decorators use this one:

public function __construct( \Aimeos\MShop\Service\Provider\Iface
$provider,
\Aimeos\MShop\Context\Item\Iface $context,
\Aimeos\MShop\Service\Item\Iface $serviceItem );

Both have their own interfaces (Provider/Factory/Iface.php and
Provider/Decorator/Iface.php) and the Factory interface isn't used for
decorators and vice versa. Despite that fact, PHP7 complains that the
decorators doesn't implement the Factory interface.

I've stripped the source code down as much as possible (classes and
interfaces are mostly empty) and pushed it to a GitHub repository:
https://github.com/nos3/php7

Furthermore, on travis-ci a test against 5.6 and 7.0 have been done:
https://travis-ci.org/nos3/php7

Expected result:
----------------
No error like for PHP 5.6

Actual result:
--------------
PHP Fatal error:  Declaration of
Aimeos\MShop\Service\Provider\Decorator\Base::__construct(Aimeos\MShop\Service\Provider\Iface
$provider, Aimeos\MShop\Context\Item\Iface $context,
Aimeos\MShop\Service\Item\Iface $serviceItem) must be compatible with
Aimeos\MShop\Service\Provider\Factory\Iface::__construct(Aimeos\MShop\Context\Item\Iface
$context, Aimeos\MShop\Service\Item\Iface $serviceItem) in
/home/vagrant/Code/Laravel/php7/Provider/Decorator/Base.php on line 20
