For seamless integration with the NIO.2 File API provide a CIFS File System Provider: http://docs.oracle.com/javase/7/docs/technotes/guides/io/fsp/filesystemprovider.html
The jCIFS product is not available anymore. Is this the right place to file jCIFS issues?
...and this "product" is for the Linux in-kernel CIFS vfs. You may want to email the jCIFS mailing list. Looks like the info is here. http://jcifs.samba.org/
