Subject [jira] [Created] (COMPRESS-380) Support for ENHANCED_DEFLATED (Deflate64) in ZIP files
Date Wed, 25 Jan 2017 15:14:26 GMT
Dawid Weiss created COMPRESS-380:

             Summary: Support for ENHANCED_DEFLATED (Deflate64) in ZIP files
                 Key: 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:
UnsupportedZipFeatureException: unsupported feature method 'ENHANCED_DEFLATED' 
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).
