Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Android Play Billing Needs updating
This was resolved in this issue: https://github.com/codenameone/CodenameOne/issues/3706

Backward Compatibility, Go 1.21, and Go 2
Naturally depends on the use case, yet they work good enough to be in business for 20 years.

Android 5 & 6 (only changed back into JIT/AOT due to long compile times), https://www.infoq.com/news/2014/07/art-runtime/
Unfortunely the best well known, Excelsior JET, is no longer in business, most likely due to GraalVM and OpenJ9 being available as free beer, while PTC, Aicas Codename One are safe in their domains.
There is also RoboVM (https://github.com/MobiVM/robovm) as free beer, however it actually started as a commercial product, and the acquisition from Xamarin kind of stagnated it (naturally).

Can't Reproduce a Bug?
At Codename One, we were using App Engine when our daily billing suddenly skyrocketed from a few dollars to hundreds. The potential cost was so high it threatened to bankrupt us within a month. Despite our best efforts, including educated guesses and fixing everything we could, we were never able to pinpoint the specific bug. Instead, we had to solve the problem through brute force.

Mobile Apps with Java
We don't use GraalVM since our project was developed prior to its existence and we aimed for deeper native integration than it can offer: https://github.com/codenameone/CodenameOne

The Holy Grail of Java Performance
We use ParparVM which we wrote. It compiles a subset of Java 8 (sort of) to native by translating the bytecode to C and passing that through XCode. The reason we took this path and not the path of "direct to native", is that it allows for future compatibility.

3D and 2D: Testing out my cross-platform graphics engine
Thanks - that link does not appear to be open access, anyways I don't think I've seen it. I'm familiar with Flutter at a high-level (Kevin Moore gave a great talk on it at Wasm I/O), and I think other than requiring users to work in Dart, it is probably one of the most powerful ways to do cross-platform UI today.
Worth noting that their original GPU backend was Skia, and now they are retooling around Flutter GPU (Impeller)[0], which is kind of designed similarly as an abstract rendering interface over platform-specific GPU APIs.

Python dev considering Electron vs. Kivy for desktop app UI
If you are considering Electron/React then I would suggest adding Flutter to your list of technologies to consider. It uses Dart (a language similar to C#) and has a lot going for it… relatively quick to get up to speed with, fantastic developer experience (e.g., hot reload, great IDE support, good development tools) and very strong cross-platform support: it generates native iOS, Android, MacOS, Windows and Linux executables.
