It's not possible to do this because you don't know who has
implemented the API. The whole point of having a stable API is to
protect people's investment in extension modules. That means it needs
to not only be source compatible, but binary compatible as well.
There are well known methods for doing this without breaking things.
You need to define a new interface
CodeGenerator2 extends CodeGenerator {
boolean superSpecialClassFilter();
}
And then have the caller conditionalize its behavior based on whether
it's a new-style or old-style module.
But I still think it could be done without changing the API...
