          Priority: P2
            Bug ID: 53503
          Assignee: notifications@ant.apache.org
           Summary: Zip archives cannot be opened by Winzip if more than
                    65535 entries are present
          Severity: normal
    Classification: Unclassified
                OS: Windows XP
          Reporter: sebb@apache.org
          Hardware: PC
            Status: NEW
           Version: unspecified
         Component: Compress Antlib
           Product: Ant

This was triggered by problems with OpenOffice.org source zip archives, see:

https://issues.apache.org/ooo/show_bug.cgi?id=120132

Ant 1.8.4 zip task creates an invalid zip archive when more than 65535 entries
(files/folders) are included in the archive.

The zip files are still usable with 7-Zip, but cannot be used with Winzip, and
WindowsZP compressed folders does not like them either.

The same set of files can be compressed with 7-Zip and Winzip will read the
archive.

In fact the same set of files can be compressed using Commons Compress (trunk)
and Winzip can read the archive.
