There's no Java stack—there should be a tower of green Java methods—instead there's only a single green frame or two. This is how Java flame graphs looked at the time. Later that year I prototyped the c2 frame pointer fix that became -XX:+PreserveFramePointer, which fixes Java stacks in these profiles.

We had our first Studio applications consuming the federated graph, without any performance degradation, by the end of the 2019. This gives us access to Netflix’s Java ecosystem, while also giving us the robust language features such as coroutines for efficient parallel fetches, and an expressive type system with null safety.
