Description

I came across custom annotations: https://github.com/janino-compiler/janino/tree/9ef0cfa9057167739211912da564054a7f3083d7/commons-compiler/src/main/java/org/codehaus/commons/nullanalysis

Just in case, janino-compiler targets Java 1.6, so it looks like they can't use type annotations yet.

Is there a way to make checker-framework understand janino-compiler nullability annotations?

I guess janino-compiler project wants to have zero-dependencies (which makes sense as the compiler is often embedded in weird class generation use-cases).
Is there something like astub for annotations in checker-framework?
Is there a way to write zero-dependency code yet make it compatible with checker-framework analysis?
