Stefan Bodewig commented on COMPRESS-380: ----------------------------------------- [~chalmagr84] having "only" decompression support would be a big step forward. The same is true for bzip2 inside of zip archives as well, for example. WRT developer access, what Dawid said. You can attach a patch here or create your own fork on github. > 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). > https://github.com/madler/zlib/tree/master/contrib/infback9 -- This message was sent by Atlassian JIRA (v6.4.14#64029)
