/** |

* Provides a proxying implementation of {@link OptionalDeploymentManagerFactory}. |
| 60 |
* Handles optional <code>noInitializationFinish</code> attribute as a way |
| 61 |
* to prevent delegate's {@link #finishServerInitialization()} to be called. |
| 62 |
* This can be useful in situation when we want to prevent loading unnecessary |
| 63 |
* code (from delegate) being loaded during the {@link #finishServerInitialization()} |
| 64 |
* call. Designed to be used via XML layer filesystem. |
