Unfortunately the need for a 8u backport was not mentioned in the review 
thread:

http://mail.openjdk.java.net/pipermail/hotspot-dev/2014-June/014453.html

Did anyone flag this since 8048169 was pushed? I can't seem to find any 
email thread on it.

I think we have a hole in the process when the "bug tail" for a 
backported fix is not also identified as needing an urgent backport.

See review thread:

http://mail.openjdk.java.net/pipermail/hotspot-dev/2014-August/014825.html

Not sure if it has been been pushed anywhere yet.
