Actually, I think y'all should do 3 things:
- backport Kumar's bug fix to jdk7
- introduce a system property to turn off the zip64 support.
I am working on a patch to introduce such a system property.
We will probably default to disabling zip64 by default, but you will
probably find that unacceptable.  But you can default the other way.
- fix up some remaining largefile issues in parse_manifest
I might contribute a bit of code here as well.
