I think this looks good overall.

Once you do your next set up updates, I will run it through mach5 for you

src/jdk.jartool/share/classes/sun/tools/jar/Main.java line 73:

> 71: import static java.util.jar.JarFile.MANIFEST_NAME;
> 72: import static java.util.stream.Collectors.joining;
> 73: import static java.util.jar.JarFile.INDEX_NAME;

Maybe move this above the java.util.streamCollectors.joining import

Also, the copyright should probably be updated to 2021

test/jdk/sun/misc/JarIndex/JarIndexMergeTest.java line 25:

> 23: 
> 24: /*
> 25:  * @test

Probably should update the copyright year to include 2021
