[13u] RFR: 8229888: (zipfs) Updating an existing zip file does not preserve original permissions

[Andrew Brygin]

Hello

 I would like to backport the fix for JDK-8229888 to jdk13u (13.0.4):

Bug: https://bugs.openjdk.java.net/browse/JDK-8229888
Original changeset: https://hg.openjdk.java.net/jdk/jdk/rev/798c0903fcd0
Webrev: http://cr.openjdk.java.net/~bae/13u/8229888/webrev.00/

 The original change does not apply cleanly due to context difference:

<      private IndexNode getInode(byte[] path) {
<          return
inodes.get(IndexNode.keyOf(Objects.requireNonNull(entryLookup.apply(path),
"path")));
---
>      IndexNode getInode(byte[] path) {
>          return
inodes.get(IndexNode.keyOf(Objects.requireNonNull(path, "path")));

 and it also requires import adjustments in 13u:

> @@ -43,6 +43,8 @@
>  import java.nio.file.*;
>  import java.nio.file.attribute.FileAttribute;
>  import java.nio.file.attribute.FileTime;
> +import java.nio.file.attribute.PosixFileAttributes;
> +import java.nio.file.attribute.PosixFileAttributeView;
>  import java.nio.file.attribute.UserPrincipalLookupService;
>  import java.nio.file.spi.FileSystemProvider;
>  import java.security.AccessController;

 The backport has been tested with tier1, and newly introduced
regression test.

Thanks,
Andrew
