* This class is created by the container and handed over to the JACC provider. This lets the JACC provider use the
* information in making authorization decisions, if it wishes to do so.
*
*
* Instead of having separate classes for each handler, we only implement one handler that handles all
* requests for the context objects. This class implements the PolicyContextHandler interface, but resolving
* of the actual objects is delegated to {@link PolicyContextHandlerData}.
