[jira] [Commented] (COMPRESS-380) Support for ENHANCED_DEFLATED (Deflate64) in ZIP files

["Christian Marquez Grabia (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/COMPRESS-380?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16245003#comment-16245003 ] 

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.

> 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).
