Subject [jira] [Commented] (COMPRESS-494) ZipArchieveInputStream component is throwing "Invalid Entry Size"
Date Sat, 12 Oct 2019 10:43:00 GMT

    [ https://issues.apache.org/jira/browse/COMPRESS-494?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16949997#comment-16949997

Stefan Bodewig commented on COMPRESS-494:
-----------------------------------------

[~anveshmora]we can also arrange for sharing an archive in a non-public way.

The real question, independent of a concrete archive, is how has the archive been created
and why does it claim to have entries with a negative size. Here it really would help to have
access to the local file header and the central directory entry - I don't really need the
file's contents, just the metadata stored inside of the zip in binary form.
