Concurrently to Andrew I also worked on a fix for JDK9 and came up with
a somewhat different approach (based on jdk9/dev):

http://tdaitx.github.com/openjdk-webrev/rh1191652-jdk9/webrev.00/hotspot/
http://tdaitx.github.com/openjdk-webrev/rh1191652-jdk9/webrev.00/root

To make it easy I already rebased Andrew's JDK8u31 patches to jdk9/dev
(due to that the webrev ended up with my username).

http://tdaitx.github.com/openjdk-webrev/rh1191652-jdk9/ahughes-webrev.00/jdk
http://tdaitx.github.com/openjdk-webrev/rh1191652-jdk9/ahughes-webrev.00/root

I tested both approaches by building Hadoop (which triggered some
interesting bugs on various projects due to Jigsaw).

Sorry for the github links, but I don't have an account at
cr.openjdk.java.net that I can use. I can provide tar files if anyone is
willing to host those webrevs.
