Hi,

Please approve the backport of this important bugfix to 8u: Bug: https://bugs.openjdk.java.net/browse/JDK-8175887 JDK 9 changeset: http://hg.openjdk.java.net/jdk9/hs/hotspot/rev/2ff05d967fb2 Compiler folks agree with backport, and nightlies seem clean: http://mail.openjdk.java.net/pipermail/hotspot-compiler-dev/2017-March/025767.html JDK 8u webrev: http://cr.openjdk.java.net/~shade/8175887/webrev.04.8u/ Product change applies cleanly, but test needs to change j.i.m.Unsafe to s.m.Unsafe. Testing: Linux x8664/release hotspot/test/compiler/c1 before/after the fix. Need a sponsor to push. Thanks, -Aleksey
