Madhu Gopanna updated COMPRESS-608:
-----------------------------------
Attachment: pax-bad-hdr-file.tar
sparse-formats.tar
> Corrupt Tar decompression fails to find all available entries
> -------------------------------------------------------------
>
> Key: COMPRESS-608
> URL: https://issues.apache.org/jira/browse/COMPRESS-608
> Project: Commons Compress
> Issue Type: Bug
> Affects Versions: 1.21
> Reporter: Madhu Gopanna
> Priority: Major
> Attachments: pax-bad-hdr-file.tar, sparse-formats.tar,
> writer-big-long.tar
>
>
> Attached are three Tars that fail to find all available entries (contents)
> and exit with an IO Exception. This change in behavior maybe related to
> specific change log in 1.21 when compared to 1.20 behavior for the same Tars.
