I see,
Java the language is not the lingua franca anymore because there is no 
way to emit an invokedynamic in Java. It causes us trouble now, and it 
starts to be worst for our users too.

A SAM converted object acts as proxy with all the known limitation due 
to the fact that a proxy is another object that the object you want to 
manipulate.

So the real solution is to have a way to emit an invokedynamic in Java 
that acts as a kind of dual of the dynamic keyword of C#.
