Madhu Gopanna created COMPRESS-609:
--------------------------------------
Summary: Corrupt Bz2 decompression fails to find all available
entries
Key: COMPRESS-609
URL: https://issues.apache.org/jira/browse/COMPRESS-609
Project: Commons Compress
Issue Type: Bug
Affects Versions: 1.21
Reporter: Madhu Gopanna
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.
