Bug: https://bugs.openjdk.java.net/browse/JDK-8176100
Webrev: http://cr.openjdk.java.net/~phh/8176100/webrev.8u.01/

Original patch: http://hg.openjdk.java.net/jdk9/jdk9/hotspot/rev/b163435e40b3

Patch applies cleanly net of file names and line numbers, except that shell scripts are necessary for jdk8 to run the two new tests. Also, I don’t have facilities to test x86 32-bit, sparc or ppc, so I’d greatly appreciate someone trying it on those platforms.
