Java 7 comes with NIO2, "New I/O version 2", stupid name I know, but it's packing some extremly important functions.
New functions that will enable us to do faster indexing, trace changes in filesystems and read more file attributes such as users and groups.
I have been waiting for this since early 2002 when the poposal for NIO2 came. I almost gave up hope on Java since then.
This makes it possible to update some core I/O functions in corpus and in our public java libraries for indexing.
