The zip64 fix looks okay to me. The fix to sync() is okay too although I 
would change this to use try-with-resources.

On the test, I agree an automated test might be too slow to run. 
However, as zip64 is tricky to get right then having a sanity test in 
the test tree (without a @test tag) would be useful.
