Please, review the jdk 9 fix for:

9 hotspot webrev:
http://cr.openjdk.java.net/~sspitsyn/webrevs/2015/hotspot/8076579-JVMTI-pop.1
Summary:
This bug is a regression that was introduced but the fix of:
https://bugs.openjdk.java.net/browse/JDK-7187554
The bug is in the InterpreterRuntime::member_name_arg_or_null()
function that
does not return NULL if there is no invokestatic appendix argument
(MemberName).
It is why the _remove_activation_preserving_args is trying to to
restore unexisting
appendix argument when a pop instruction is executed by a debugger in
the debuggee VM.
The fix is to correctly set NULL in the thread vm_result when it is
necessary:
thread->set_vm_result(NULL);
Testing in progress:
In progress: nsk.jvmti.testlist and nsk.jdi.testlist PopFrame tests,
JTREG com/sun/jdi tests,
ad-hog ExceptionBug.java test from the bug report
Thanks,
Serguei
