Question regarding "native-compiled frame"

[Felix Yang]

Hi,

  Thanks for the reply.
  Then when will the last return statement of frame::sender got a chance to
be executed?
  As I see it, when JVM does something in safepoint state and need to
traverse Java thread stack, we never calculate the sender of a
native-compiled frame.
  Except for running Specjbb, I also performed a full jtreg test in order
to catch one such case, but still the last return statement not hit.
  So it's strange to me that frame::sender needs to handle such a frame.
  Maybe I missed something.  Could you elaborate more on this please?

Thanks for your help,
Felix
