The updated webrev looks must better. In JarURLConnection then it would 
be good if the reference to multi-release JARs should link to the 
description in the JarFile spec.

In the previous round then we were discussing renaming the 
jdk.util.jar.multirelease property. Has there been any more on that?

The test MultiReleaseJarURLConnection uses @library 
/lib/testlibrary/java/util/jar so it's reaching across the file system 
to use the infrastructure of the JarFile tests. It might be clearer to 
move the test to the JarFile directory.

It would be nice if we could reduce some of the really long lines if 
possible, just to make future side-by-side a bit easier (avoid 
horizontal scrolling).
