Stefan Bodewig commented on COMPRESS-417:
-----------------------------------------
The archive contains the value "dos" where the "major device number" is
expected in ustar tar archives. After reading what the GNU tar and BSD tar
pages say, we should probably ignore devmajor and devminor unless the file type
is a character or block special file.
> Decompress tar.gz file failed. java.io.Exception:Error detected parsing the
