I skimmed through this and it looks quite. I just wonder if we should 
check in the micro benchmarks as it is likely we'll need those again in 
the future.

One thing that isn't clear (to me anyway) is the change to detecting 
\u0000 in the normalization code. Do we have any cases where 
IllegalPathException is thrown?

In checkAccess there is a comment about needing to read the CEN. It this 
method needed? I would check that ZipFileSystemProvider should just need 
to invoke exists (+ checks when w or x modes).

In cen then the versionMade-attrsEx is commented out, should they be 
removed?
