Greetings,

I've tweaked the fix based on Vladimir's feedback.

Here is the URL for the second round webrev:

http://cr.openjdk.java.net/~dcubed/8049717-webrev/1-jdk9-hs-rt/

The following files changed between round 0 and round 1:

src/cpu/sparc/vm/vm_version_sparc.cpp
src/cpu/x86/vm/vm_version_x86.cpp
src/cpu/x86/vm/vm_version_x86.hpp
src/share/vm/runtime/objectMonitor.cpp
src/share/vm/runtime/synchronizer.cpp

Thanks, in advance, for any comments, questions or suggestions.

Dan
