I ran into a situation in which DI is attempting to inject the wrong options parameter to an incorrect 'dependant' class.


but it boils down to DI trying to inject 'my-service-configuration' as options to Filesystem which is an CacheAdapter instantiated by the CacheFactory::factory

<pre class="highlight">
'My\Service' => array( /* LocatorAware, LoggerAware, mimic CacheAware */ 
                'parameters' => array( 
                    'options'      => 'my-service-configuration', /* is a My\ServiceOptions instance */ 
                    'logger'       => 'my-logger', /* is a Logger instance */ 
                    'cache'        => 'my-cache-adapter',  /* is a AdapterInteface instance */

Changing My\Service constructor to consume $serviceOptions is has been confirmed to avoid this problem.
