Not Java.  You might ask Andrea about CLR though.

Java has 2 kinds of indirect function call (to be precise, this is the
"C++ ABI".  The binary compatibility ABI is different -- but also
isn't open to this kind of optimization).  Virtual calls are
implemented in a way that is compatible with C++.  Interface calls are
implemented in a different way.
