[8u-dev] Request for approval for CR 8150426: Wrong cast in metadata_at_put

[Kevin Walls]

Hi,

I'd like to request approval to backport from 9 to 8u:

8150426: Wrong cast in metadata_at_put
JBS: https://bugs.openjdk.java.net/browse/JDK-8150426

This fixes a build error if you vary the compiler from our defaults.

9 changeset:
URL:   http://hg.openjdk.java.net/jdk9/jdk9/hotspot/rev/e06c15b0844e
(diff pasted below)

9 review thread:
http://openjdk.5641.n7.nabble.com/RFR-8150426-Wrong-cast-in-metadata-at-put-td258746.html

This is a clean backport, or imports with minimal/trivial changes.

Thanks!
Kevin
