Nah. At least, not in mojarra-2.0.3.
This is from
com.sun.faces.application.resource.ResourceHandlerImpl#handleResourceRequest
:
resource =
context.getApplication().getResourceHandler().createResource(resourceName,
libraryName);
However, I don't know if there is any gotcha of the kind you pointed out.
I have to code my own handleResourceRequest method anyway, so.

Eh, you're right.
Now I see
com.sun.faces.config.processor.AbstractConfigProcessor#createInstance works
that way...
Thank you very much.
Shouldn't this be better stated in the JSF specs?
