I think there's a discussion point there as Path is an interface and 
there are different concrete types. In any case, we can't change this of 
course.

The toFile() method is meant for interoperability with the legacy API 
and so some care is required to avoid using it on Paths to objects in 
arbitrary file system that could not be represented by java.io.File. I 
think I'd need to see more context to know if you should be propagating 
anything or whether the issue is just an incorrect assumption somewhere.
