Dawid Weiss commented on COMPRESS-380:
--------------------------------------
I'm not a committer, but I looked at the patch and while I didn't verify its
correctness I think it's overall looking very neat -- congratulations. Stefan
may correct me, but I think you'll need to add Apache headers to source files
if you'd like this to be merged in. Are those classes all authored by you
(they're looking awfully nice)!?
Also, is there any reason your comments are not visible to the world? It'll
look strange to non-jira users to just see our replies.
> 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

> 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).
