Hi,
Please review this change which fixes buggy behavior (including SEGV) in
the experimental LiveStackFrame feature of StackWalker.
Bug:
https://bugs.openjdk.java.net/browse/JDK-8147039
Webrev:
http://cr.openjdk.java.net/~bchristi/8147039/webrev.02/
As suggested in the bug report, stack walking is reimplemented using
javaVFrame/vframe::java_sender. The native StackWalkerAnchor class is
updated (and renamed) with a similar interface and function to
vframeStream. I've also removed the now-unneeded
vframeStreamCommon::java_frame() function, added by 8140450.
Thanks,
-Brent
