Path.createFile() and Path.createDirectory() throw NoSuchFileException if parent doesn't exist (Windows)

[Vince Bonfanti]

I notice that on Windows both Path.createFile() and
Path.createDirectory() throw a NoSuchFileException if their parent
directory doesn't exist. Is this expected behavior for all file
systems, or is it optional for a file system to create the parent
directories if they don't exist? In either case, it should documented
in the Javadocs.
