I think the code that renames duplicate methods is in LambdaExp.java
around line 1156,

Looking more, it looks like Kawa does support co-variant return types.
(Kawa is so big and so old I don't remember everything in it ...)
See generateBridgeMethod in ClassExp.java.

It seems to me you can either have:
     ((apply (ctx ::io.jooby.Context)) ::string ...)
or:
     ((apply (ctx ::io.jooby.Context)) ::java.lang.Object ...)
but not both.

The former uses co-variant return types, and it is quite
possible there is a bug in the Kawa compiler in that area.
So if that doesn't work, use the latter.

I don't know how Jooby introspection works.
Looking at Java source files feels like a weird thing to do.
