[Peter Zhelezniakov]

Hi,

This is the final backport request in a series of 3: [1], [2], [3]. The patch did not apply cleanly because context has changed significantly.
Tested with Hotspot JTreg tests.
JBS issue: https://bugs.openjdk.java.net/browse/JDK-8231501
Webrev: http://cr.openjdk.java.net/~avoitylov/peterz/8231501/8231501/

Thanks!
Peter
