> Consider custom renderer with @ResourceDependencies (and many @ResourceDependency here).
If a view has 500 UIComponent with this custom renderer, ApplicationImpl._handleAnnotations
process the same set of ResourceDependecies again and again.
> With my test scenario, VDL.buildView takes therefore  750ms. After small modification
in ApplicationImpl _handleAnnotations it takes only 70 ms. 
> The modification can be like:
> Class<?> inspectedClass = inspected.getClass();
>      
> // Process annotation only if this is the first creation of component(renderer,validator,
converter) of particular type in this request/response
>         if (! context.getAttributes().containsKey(inspectedClass.getName())) { 
>         _handleListenerForAnnotations(context, inspected, inspectedClass, component,
isProduction);
>         _handleResourceDependencyAnnotations(context, inspectedClass, component, isProduction);
>     // Remeber here that this class and it's dependencies are in viewRoot.componentResources

>             context.getAttributes().put(inspectedClass.getName(), Boolean.TRUE);
>         }
> ;
> But I'm not sure what specification says about this processing.
