> We've recently updated commons-compress library from version 1.9 to 1.20 and 
> now experiencing the problem that didn't occur before.
>  
> When using ZipArchiveOutputStream to archive 5Gb file and setting the 
> following fields
> {{output.setUseZip64(Zip64Mode.Always)}}
>  
> {{output.setCreateUnicodeExtraFields(ZipArchiveOutputStream.UnicodeExtraFieldPolicy.ALWAYS)}}
> resulting archive contains corrupted headers.
> *Expand-Archive Powershell utility cannot extract the archive at all with the 
> error about corrupted header. 7zip also complains about it, but can extract 
> the archive.*
>  
> The problem didn't appear when using library version 1.9.
>  
> I've created a sample project that reproduces the error - 
> [https://github.com/missingdays/commons-compress-example]
> Issue doesn't reproduce if you do any of the following:
>  
>  # Downgrade library to version 1.9
>  # Remove 
> output.setCreateUnicodeExtraFields(ZipArchiveOutputStream.UnicodeExtraFieldPolicy.ALWAYS)
>  # Remove output.setUseZip64(Zip64Mode.Always) and zip smaller file (e.g. 1Gb)
