I tested by adding a `System.out.println` to `MethodTypeDesc.ofDescriptor` and
it printed nothing locally when running this little program including string
concat and lambda with `java Ape` (Note that `java Ape.java` will print
gibberish once`, didn't diagnose that one yet):
public interface Ape {
static void main(String... args) {
Runnable a = () -> {
System.out.println("asd[" + args[0] + "foo" + args[1]);
};
a.run();
}
}
Before a cache miss call looked like this:
