With 2.0 tar is supported out of the box, with 2.1 it is not. It depends
on commons-compress which is listed as an optional dependency.
Is this intentional? If so the documentation
(http://commons.apache.org/proper/commons-vfs/download.html) needs to be
updated prior to release.

The default manager configuration in providers.xml registers the Tar
and Bzip2FileProvider conditionally based on commons compress classes.
For GzipFileProvider it uses unconditionally the java.util.zip package.
