I have too many things on my plate, it is yours and Jon to call on this.

This bug should just be fixed - I'm guessing it's 20 lines of code or so.

We can live with this bug because we can just turn off optimized zip in javac, but it would be nice to have the optimzed version work correctly, and I might be able to cook up a fix if no one else is going to volunteer to work on it. Let me know.

The thorny compatibility issues are indeed hard (seriously, the risk and effort of a ZIP64 backport is too high and the value provided too low), ..... but for the issue of jdk7 javac not understanding jdk6-created jar files with >64k entries, I suggest "simply" fixing the code as I outlined and adapting T6836682 to a non-jtreg test (because it would need both a jdk6 and a jdk7 as inputs).
