I was thinking of zip api’s other than java’s. The field needs to be at a fixed place in the file format whatever the name? Unless a significant api change has been made.
A couple of links from googling on “zip extra field chaining" https://libzip.org/specifications/extrafld.txt https://www.hackerfactor.com/blog/index.php?/archives/405-Keeping-Zip.html If this were strictly jar files I would be less concerned but zip is widely used outside of java so more chances for conflict where java doesn’t have anything like ownership. At the time I looked at it the provision for “user” additions was very limited again making conflict more likely. > On May 12, 2024, at 9:32 PM, - <liangchenb...@gmail.com> wrote: > > Hi Mike, > I think this particular field has been renamed a few times; and ZipEntry only > exposes part of the ZIP format's fields.
