Hi Serguei,
Thank you for the review.
The issue is described in CSR in details.
Short summary:
A NotifyFramePop request is only cleared if the JVMTI_EVENT_FRAME_POP is
enabled. The problem is that if a NotifyFramePop request is not cleared
when the JVMTI_EVENT_FRAME_POP events notification is disabled, then an
unrelated FRAME_POP event is sent after the notification is re-enabled
(test in the fix demonstrates the scenario).
Changes in jvmtiExport.cpp updates updates methodExit handler to clear
pending FramePop events even if JVMTI_EVENT_FRAME_POP is disabled.
Changes in jvmtiEventController.cpp turns on interp_only_mode if
NotifyFramePop is requested (this is also for the case when
JVMTI_EVENT_FRAME_POP is disabled).

Hi Alex,
Looks good.
Thank you a lot for taking care about this!
I know, it was not easy to sort out the regressions observed in testing.
Could you, please, explain the issue and fix to reviewers?
Thanks,
Serguei
