| Simple caching mechanism used to manage portlet descriptors. This mechanism
takes special considerations to make sure that the cache is invalidated for
any ServletContext that is destroyed, thus allowing for a the context to be
redeployed.
NOTE: This should only be used internally. Do not access it from embedding
portals, instead, utilize the PortletRegistryService.
