/**
* The dynamic class loader manager is a central
* service managing all dynamic class loaders.
* It provides a class loader that can be used by
* bundles requiring access to all publically available
* classes.
*
* The default implementation uses the package admin
* service to load classes and resources.
*
* Keep in mind, that the class loader might get invalid.
* This happens for example, if the class loader loaded
* a class from a bundle which has been updated in the
* meantime. Or a dynamic class loader provider has changed.
*
* In these cases, the dynamic class loader manager service
* is unregistered and reregistered again, so you should
* discard your classloader and invalidate loaded objects
* whenever this happens.
