Stefan Bodewig commented on COMPRESS-380:
-----------------------------------------
I just realized the patch only works for ZipFile and not for
ZipArchiveInputStream which is fine with me. It shouldn't be too difficult to
add support to the stream as well, I'll take care of that.
> Support for ENHANCED_DEFLATED (Deflate64) in ZIP files
> ------------------------------------------------------
>
> Key: COMPRESS-380
> URL: https://issues.apache.org/jira/browse/COMPRESS-380
> Project: Commons Compress
> Issue Type: New Feature
> Reporter: Dawid Weiss
> Fix For: 1.16
>
> Attachments: archive-deflate.zip, archive-deflate64.zip,
> compress-380.diff, hello.world
>
>
> Some of the (large) ZIP files we try to process currently will throw this:
> {code}
> UnsupportedZipFeatureException: unsupported feature method
> 'ENHANCED_DEFLATED'
> {code}
> which is a bummer since JDK's implementation also doesn't support Deflate64.
> This seems to be PKWare's extensions, although code to decrypt it exists in
> zlib (and is appropriately licensed, I believe).
