When a reference to an external object (e.g., a Java one, or one in a 
remote process) is brought in over the binary UNO to C++ bridge, a fake 
C++ object is created as a proxy for that external object, and that fake 
object's vtable function pointers pointer at such dynamically generated 
stubs.

On the other hand, when directly calling from C++ to C++, no bridging is 
involved.
