JDK-8223771 - (zipfs) FileSystemProvider.newFileSystem(Path, Map) should throw IOException when called with a file that cannot be open
Description
Summary
-------

Invoking `java.nio.file.FileSystems.newFileSystem(Path)` to create a Zip file system throws `FileSystemNotFoundException` instead of `IOException` when the Zip or JAR file does  exist (the `create` option is not specified).

Problem
-------

Since the original Zip FS prototype in JDK 7, the Zip FS incorrectly throws `FileSystemNotFoundException` when the specified Zip or JAR does not  exist  and is not being created.

Solution
--------

Zip FS will throw a `NoSuchFileException`, which is a subclass of IOException, if the file does not exist and is not being created.



Specification
-------------

There is no change required to the specification.
Comments
I see a release note is already planned. Moving to Approved.
