That does not help. The File/path is not stored with the instance. It is in
a map FSDirectory keeps statically. Should subclasses of FSDirectory be
modifying the map?
This is not a question about how to subclass or customize FSDirectory. This
is more on how to use NIOFSDirectory class. I am hoping for a simply answer,
is what I am doing (setting the class name statically on system property)
the right way?
