Major Description
The code we have on resource api is very useful. It should be on shared, to make easier implement custom ResourceHandler classes.
For example, in tomahawk the class CAPTCHAResourceHandlerWrapper requires to handle the mapping for the current request.
But there are classes that are myfaces specific, like InternalClassLoaderResourceLoader (used to show sources on development time), ResourceHandlerImpl or DefaultResourceHandlerSupport.
