      The attached test VarHandleTestAccessBoolean.java fails only on windows_x64_6.3-product.

      To test apply the following patch to jdk9/dev/jdk:

        http://cr.openjdk.java.net/~psandoz/jdk9/JDK-8161444-vhs-bitwise-atomics/webrev/

      compile with:

       javac --add-exports java.base/jdk.internal.misc=ALL-UNNAMED VarHandleTestAccessBoolean.java

      and run with the attached run.sh script.

      So far it has not been possible to reproduce on any other platform other than windows_x64_6.3-product.
