Description

FileUtils.listFiles() returns only files and not directories.
So it can't be used to retrieve sub-directories.

Some fix could be applied:

 private static void innerListFiles(Collection files, File directory,
            IOFileFilter filter) {
        File[] found = directory.listFiles((FileFilter) filter);
        if (found != null) {
            for (int i = 0; i < found.length; i++) {
                if (found[i].isDirectory()) {
>>> fix
                    if ( addDirectories ) {
                       files.add(found[i]);
                    }
>>> end fix
                    innerListFiles(files, found[i], filter);
                } else {
                    files.add(found[i]);
                }
            }
        }
    }
