Thanks Daniel!

Maybe, in the future, we could dump node information in a more structured manner? E.g., `dump_spec_json` or similar. I guess it's probably too much work for too little gain.

I agree that that would be more robust, on the other hand using the available `dump_spec` information means that the filter can be readily used to inspect graphs generated from older JVM versions, without having to backport HotSpot changes.
