[compress] differences in implementation of Zip ibm vs. oracle?

["Allison, Timothy B." <ta...@mitre.org>]

Compress colleagues,

  Over on https://bz.apache.org/bugzilla/show_bug.cgi?id=61275, a user submitted two .xlsx files generated with Apache POI, one by IBM's jvm and one by Oracle's jvm.  The file generated with Oracle's jvm opens without issue; however, MSOffice complains but can fix the file generated by IBM's jvm.  Winzip opens both without complaining.

  Does this ring a bell?  Have you seen this before?  Anything we can do on our (POI's) side to fix this?

   Thank you.

             Best,

                       Tim

Is this jdk 8 vs.  java SDK 8? The oracle code picked up some fairly big
changes along the way that aren't present in the IBM library.  (jdk 9 is
really different from both. I haven't seen what the IBM Java 9 is like
yet).

I will see if anything looks blatantly obvious.
