RFR(XS): JDK-8068655 frame::safe_for_sender() computes incorrect sender_sp value for interpreted frames

[Frederic Parain]

Andrew,

I haven't produce a unit test because it is really tricky to trigger
with current HotSpot code. However, I'm working on a project where
stack walking is performed when a stack overflow error is detected.
When I used my modified VM to execute 
hotspot/test/compiler/uncommontrap/TestStackBangMonitorOwned, I hit this 
bug.

Regards,

Fred
