     I think it's worth a short comment to keep someone from
     "optimizing" this in the future:

                   // need the current JavaThread and not thread():
     line 272:     methodHandle m_h(method());

     And if you could add the same comment above:

                     // need the current JavaThread and not thread():
     line 333:       methodHandle m_h(method());
