D is already virtual, since inherits a virtual function.
The point ofupcast is to introduce static_cast or dynamic_cast when C cast doesn't work. That's not the case here. Look at my 2 suggestions at the end of the post. Doesn't one of them sound sane ?

A workaround, as long as we don't need D to be virtualized, is to add, like for torch::Module:

infoMap.put(new Info("B::f").annotations("@Virtual(subclasses=false)")

This prevents the JavaCPP_D peer class to be created.

It won't work if class D isn't Virtual as well, yes, that's expected.

Actually, that probably wouldn't work either. That sounds like the kind of thing your Info.upcast is supposed to solve...
