I tried, but getRawPath returned output/%23/dom.xml, that in turn resulted in java.io.FileNotFoundException later.

For StreamResult, when a String-form systemId is in File protocol, a FileOutputStream will eventually get created. Since StreamResult accepts OutputStream, there's no need for the File -> URI -> <file protocal> systemId -> URL -> File conversion (as did in TransformerImpl). I think it's better to create a FileOutputStream right from the File input.
