/**
* Producer method used to build instances of <code>RuntimeManager</code> automatically by CDI container.
* It contains dedicated producer methods for all supported manager types:
* <ul>
* <li>singleton</li>
* <li>per request</li>
* <li>per process instance</li>
* </ul>
* It requires two bean injected that are required for successful instantiation of <code>RuntimeManager</code>:
* <ul>
* <li><code>RuntimeEnvironment</code></li>
* <li><code>RuntimeManagerFactory</code></li>
* </ul>
*
* Injections are controlled with qualifiers so same should be used at injection points that should receive them
*

* @see PerRequest
