You might want to give it a spin on Prime (Zing) 11 and see what you get,
the Falcon JIT in Prime will do polymorphic guarded in-line caching for up
to 6 implementers by default, I believe (as is configurable to higher if
needed). This is exactly the sort of thing that capability is meant for.

Hello,
we know that there are some techniques that make virtual calls not so
expensive in JVM like Inline Cache or Polymorphic Inline Cache.
Let's consider the following situation:
Base is an interface.
public void f(Base[] b) {
for(int i = 0; i < b.length; i++) {
b[i].m();
