ZipInputStreamexpects all archive entries to immediately follow the previous one. This is normally the case for archives created in one go, but necessarily true when they have been updated.This PR allows
ZipInputStreamto skip any padding between entries and consequently read "direct-updated" archives.Fixes #639
Curiously, 7-zip does not seem to handle these files either and just show all entries found before the first "padded" one. And of course, when updating it uses the equivalent of
ZipFilesFileUpdateMode.Safeto avoid the issue.
