[11u] RFR: 8232879: (zipfs) Writing out data with ZipFileSystem leads to a CRC failure in the generated jar file

[Jaikiran Pai]

Can I please get a review and a sponsor for a backport of
https://bugs.openjdk.java.net/browse/JDK-8232879.

The original fix for that is:

    https://hg.openjdk.java.net/jdk/jdk/rev/9d95d8a8b750

That commit does not apply cleanly on jdk11u-dev due to change in line
numbers in ZipFileSystem.java and due to usage of Filesystems API, in
the test, that do not exist in Java 11.

In my backported patch, I have manually applied the diff and also
updated the test to make it use FileSystems.newFileSystem(...) APIs that
do exist in Java 11. The usage of these different API for
FileSystems.newFileSystem(...) shouldn't play a role in what is being
tested.

The webrev for this backport is hosted at
https://cr.openjdk.java.net/~jpai/8232879-11u-backport/1/webrev/

I have locally run the test that has been included in this patch and
also have run the tier1 tests. They have passed (there's an unrelated
failure in hotspot test in teir1):
