30  * In-Memory database of MBeanInfo objects.
31  * This is primarily used to store and load MBean info objects (and therefore, MBeans)
32  * through the persistence manager attached to this object.
33  * The MBean Registry delegates to this class the work of MBean Info persistence.
34  * This class further delegates that task to it's persistence manager. This allows
35  * MBeanInfo persistence to be managed as part of the invocation stack via the
36  * Persistence Interceptor.
