I don't think that would work. There are assumptions made by the
underlying FileSystem implementation that would undoubtledly cause
problems. For example if SmbFile extended File and you passed it to an
FileOutputStream constructor, it would call getPath which would return
an SMB URL. Then open on the FileSystem implementation would be called
which the local OS wouldn't have a clue what to do with. I suspect
there's quite a bit of this in the java.io. package. It's theoretically
possible and an interesting idea but I think it would turn out to be
more trouble than it's worth. I don't think they intended java.io.File
to be extending (at least not for networking protocols).
