Yes, the lock record could be on the native stack in either an interpreter frame or a compiled frame, but I don't know if that's what you mean by being in a compiled vframe.  If you mean what is returned by `compiledVFrame::monitors`, that returns all the monitors locked by the compiled frame, both inflated and fast/stack locked.
