On z/OS 2.2, I see:
user@OS/390.25.00:511$ cksum k4t4949b.zip
899553449 1118616064 k4t4949b.zip
(Checksums are nice; don't need to be cryptographic strength;
just anything to detect transmission errors.)

user@OS/390.25.00: jar tvvf k4t4949b.zip

OK.  There's little use in extracting a zip archive on z/OS.  Still,
if software distributed by IBM can't read documentation produced by
IBM, there's a disconnect.

Info-zip, my personal Gold Standard says:

508 $ unzip -vv k4t4949b.zip
Archive:  k4t4949b.zip
  End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
note:  k4t4949b.zip may be a plain executable, not an archive
unzip:  cannot find zipfile directory in one of k4t4949b.zip or
        k4t4949b.zip.zip, and cannot find k4t4949b.zip.ZIP, period.
