In jdk8:

1)
  a) When calling layout_activation() for size calculation, caller_actual_parameters is equal to callee_param_count (except for the bottom frame).
  b) When calling it for frame data filling, caller_actual_parameters is the number of parameters the caller passed to this frame (no relation between caller_actual_parameters and callee_param_count).

2)
  a) When calling layout_activation() for size calculation, caller_actual_parameters, callee_param_count and tempcount are not adjusted by +1 for MemberName argument.
  b) When calling it for frame data filling it receives adjusted counters.

After the fix for 8032410, 1) is fixed, but 2) remains.
