It sounds strange to mee too. I tried to reproduce the error you get but 
even if the path is wrong, I get a "Resource '<path>' does not exist." 
instead of your FileNotFoundException (i.e. "No such file or directory").

In fact, the extractor is used to adapt the loading process of the old 
RegularVM api to the new one. The ModelLoader has, for instance, a 
complex behaviour to decrypt uri's, that I don't want to break (to 
prevent compatibility issues). That explains why we remove the 
platform:/resource prefix: the ModelLoader recreates a correct uri using 
the modified path (see 
org.eclipse.m2m.atl.drivers.emf4atl.EMFModelLoader.realSave(ASMModel, 
String)).

So I can strongly simplify the implementation of the ASMExtractor (and 
injector too), making it more semantically correct, but I'm not sure it 
will solve your bug.

Could you report a bug about your issue ? Giving if possible the 
transformation project (eventually the java code you use to launch it).

Thanks in advance,

William
