*
* Dependencies between MBeans are handled by a dedicated DependencyService
* that is responsible for tracking those dependencies and ensuring that the
* dependent objects follow the appropriate lifecycle and receive appropriate
* notifications.
*
* The Kernel also provides a ConfigurationStore which is used to stage
* installed Configurations (providing a local filesystem based classpath) and
* used hold the persistent state of each Configuration. This allows
* Configurations to restart in he event of system failure.

/**
* A Configuration represents a collection of runnable services that can be
* loaded into a Geronimo Kernel and brought online. The primary components in
* a Configuration are a codebase, represented by a collection of URLs that
* is used to locate classes, and a collection of GBean instances that define
* its state.
*
* The persistent attributes of the Configuration are:
* <ul>
* <li>its unique configID used to identify this specific config</li>
* <li>the configID of a parent Configuration on which this one is
dependent</li>
* <li>a List<URI> of code locations (which may be absolute or relative to a
baseURL)</li>
* <li>a byte[] holding the state of the GBeans instances in Serialized
form</li>
* </ul>
* When a configuration is started, it converts the URIs into a set of
absolute
* URLs by resolving them against the specified baseURL (this would typically
* be the root of the CAR file which contains the configuration) and then
* constructs a ClassLoader for that codebase. That ClassLoader is then used
* to de-serialize the persisted GBeans, ensuring the GBeans can be recycled
* as necessary. Once the GBeans have been restored, they are brought online
* by registering them with the MBeanServer.
*
* A dependency on the Configuration is created for every GBean it loads. As a
* result, a startRecursive() operation on the configuration will result in
* a startRecursive() for all the GBeans it contains. Similarly, if the
* Configuration is stopped then all of its GBeans will be stopped as well.
