Resending with better subject line, hopefully HS reviewers would see it. You need to send to hotspot alias to get a code review. David

Please approve this fix for 8u. This improves G1 stability in 8u, and provides the base for Shenandoah JDK 8 backport that piggybacks on G1 pre-barriers. The fix does not apply cleanly, because there is also UnsafeGetObject140 that needs fixing too. JDK 9 bug: https://bugs.openjdk.java.net/browse/JDK-8165489 JDK 9 fix: http://hg.openjdk.java.net/jdk9/jdk9/hotspot/rev/a696583f5ddb JDK 8u fix: http://cr.openjdk.java.net/~shade/8165489-8u/webrev.01/ Testing: x8664 build, Shenandoah tests Thanks, -Aleksey
