> I'm trying to use a ZipArchiveEntry coming from ZipArchiveInputStream that I stored somwhere
for later with a ZipFile and it does not work.
> The reason is that it can't find the ZipArchiveEntry in the ZipFile entries map. It is
exactly the same zip file but both entries are not equals so the Map#get fail.
> As far as I can see the main difference is that {{comment}} is null in ZipArchiveInputStream
while it's en empty string in ZipFile. I looked at ZipArchiveInputStream and it looks like
the comment (whatever it is) is simply not parsed while I can find some code related to the
comment at the end of ZIipFile#readCentralDirectoryEntry.
> Note that java.util.zip does not have this issue. Did not checked what they do but the
zip entries are equals.
