Christian Marquez Grabia commented on COMPRESS-380: --------------------------------------------------- I have tried many other options to solve this issue but not able to... the only thing I could use to replace it is the sevenzipjbinding project but it seems to have caused some JVM crashes when running unit tests (randomly), so I'm a bit concerned about it... currently spawning a separate process to execute the native code to avoid any major issues here... Any update / suggestions on the topic would be greatly appreciated. > 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)
