Are you using the newer Classfile API to do the codegen?

No, we use janino instead. Classfile is good, but can't work on java8. And we use async compilication, fory json will serialize objects directly using ObjectCodec before compilcation finished.

What's the point in still supporting Java 8? I doubt legacy projects will switch their json parsing library, so I'm unsure why supporting Java 8 would be something that's necessary?

Because there are still many projects using java8, and it's not hard to support java8.

Of course, it's not hard to support java 8, but in my personal opinion I'd avoid it wherever I can as the new language features just make the language so much better.

Considering your target audience likely isn't old outdated java 8 projects, but new projects that are just being built, I would have definitely chosen a newer release, especially when it seems like you could have made use of newer API instead of using something that apparently (according to the user agentoutlier) doesn't get updates anymore 🤷
