When trying to use zend-cache downloaded separately via Composer (under Windows 7, fwiw), the following exception is thrown:

A plugin by the name "exception_handler" was not found in the plugin manager Zend\Cache\Storage\PluginManager

The relevant part of the stack trace:

0 ...\vendor\zendframework\zend-cache\src\StorageFactory.php(203): Zend\ServiceManager\AbstractPluginManager->get('exception_handl...')

composer.json used to download the package:

{
    "name": "test",
    "require": {
        "zendframework/zend-cache": "^2.5"
    }
}

In case of using zend-cache from ZF downloaded entirely ("zendframework/zendframework": "^2.5"), the issue is not reproduced.

Thanks.
