I read from Zend\Cache\Storage\AdapterPluginManager.php, "'xcache' => 'Zend\Cache\Storage\Adapter\XCache',". But I don't find any class named Zend\Cache\Storage\Adapter\XCache.

And when I try factory with :

$cache = Zend\Cache\StorageFactory::factory(array( 'adapter' => 'xcache', 'plugins' => array( 'exception_handler' => array('throw_exceptions' => false), ), ));

The result (predictable, but if nobody says, no reason to fix) is :

Fatal error: Class 'Zend\Cache\Storage\Adapter\XCache' not found in D:\Personnel\phpSofts\ZendFramework-2.0.0\library\Zend\ServiceManager\AbstractPluginManager.php
