Karen,
Thank you for your review, my answers are in-lined below.

Frederic,
Code review for web revs you sent out.
Code looks good. I am not as familiar with the compiler code.
I realize you need to check in at least a subset of the
java.util.concurrent changes for
the test to work, so maybe I should not have asked Doug about his
preference there.
Sorry.
I am impressed you found a way to make a reproducible test!
Comments/questions:
1. src/cpu/sparc/vm/interp_masm_sparc.cpp line 1144 “is” -> “if”
Fixed
2. IIRC, due to another bug with windows handling of our guard pages,
this
is disabled for Windows. Would it be worth putting a comment in the
bug , 8067946, that once this is fixed, the reserved stack logic on
windows
will need testing before enabling?
More than testing, the implementation would have to be completed on
Windows. I've added a comment to JDK-8067946.
3. In get_frame_at_stack_banging_point on Linux, BSD and solaris_x86 if
this is in interpreter code, you explicitly return the Java sender
of the current frame. I was expecting to see that on Solaris_sparc
and Windows
as well? I do see the assertion in caller that you do have a java frame.
It doesn't make sense to check the current frame (no bytecode has been
executed yet, so risk of partially executed critical section). I did the
change but not for all platforms. This is now fixed for Solaris_SPARC
and Windows too.
4. test line 83 “writtent” -> “written”
Fixed
5. I like the way you set up the preallocated exception and then set
the message - we may
try that for default methods in future.
6. I had a memory that you had found a bug in safe_for_sender - did
you already check that in?
I've fixed x86 platforms in JDK-8068655.
I've piggybacked the SPARC fix to this webrev (frame_sparc.cpp:635),
I had hoped it would have been silently accepted :-)
7. I see the change in trace.xml, and I see an include added to
SharedRuntime.cpp,
but I didn’t see where it was used - did I just miss it?
trace.xml changes define a new event.
This event is created at sharedRuntime.cpp::3006 and it is used
in the next 3 lines.
