I've had a difficult time finding certain methods in the JavaDoc. For instance, Opt4JModule.bindConstant is missing. I believe that JavaDoc is only generated for publicly accessible methods even though private, protected, and default methods are properly annotated. My guess is that this is a setting when JavaDoc is run.
You're right, I will change that.
You can of course also use the Guice-way: bindConstant().annotatedWith(...)...
