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

[Allison, Timothy B.]

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
