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.

Backward Compatibility, Go 1.21, and Go 2

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

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.

Unity's Licensing Changes: Discover Stride a Community-Driven Open-Source Engine
> Unfortunately, this is yet another open source game engine with too small a user base.
I wonder why some engines are seemingly destined for success and others... aren't.
Godot got really big, despite a somewhat similar feature set: https://godotengine.org/ (really nice 2D support, 3D rendering was worse until version 4, GDScript has both a nice iteration speed but also has gotten some criticism, while C# was a second class citizen in the earlier iterations)
Stride is really nice and seemed like it should have been the Unity replacement that people would look at, if it had gotten more attention and a community would have formed around it, like Godot's.
There's also NeoAxis which is way more Windows centric, but still seems to be getting updates and is comparatively easy to use, yet similarly never got popular: https://www.neoaxis.com/
Weirder yet, Java doesn't really have that many game engines out there, at least the likes of Unity/NeoAxis/Stride that have nice editors, despite the language being pretty nice. The closest I can think of is jMonkeyEngine which I donated some money in the past to, which is pretty usable but similarly niche: https://jmonkeyengine.org/
I occasionally watch videos on the Gamefromscratch YouTube channel (https://www.youtube.com/@gamefromscratch/videos) and it surprises me that there are so many engines out there, but very few actually are in the public eye. If you don't go out of your way to look for other options, you will most likely only have heard of Unity and Unreal (or maybe also Godot in recent years). I wonder why that is.

My recommendation on which language and libraries to use for the engine.
There more `bare-metal` engines like https://jmonkeyengine.org/ (well it is not C++, it is Java based)...

Are scene graphs used often in game development? and if so, are there open source scene graphs?

[Hobby] Need help implement Continuous Collision Detection in a classic top-down multiplayer space shooter
This project develops a cross-platform Subspace client and server written in Java. It was developed from scratch on the idea of extensibility and modularity. The server is based on modules/frameworks highly optimized for scaled, networked, grid-based, infinite world physics. The client is based on the JMonkeyEngine, a minimalistic modern developer friendly, open source, game engine

Godot 4.0 Stable
> Godot is one of those pinnacle FOSS projects that just totally impresses me, especially given the state its in now, with 4.0.
It is definitely one of the success stories, at least so far.
For example, there are projects like jMonkeyEngine (a game engine in Java, on top of LWJGL) that don't get as much attention and their movement forwards is way slower: https://jmonkeyengine.org/
There's also Stride 3D, which is a bit closer to Unity I'd say, which is still a really nice project, but is also limited in how much development can be done: https://www.stride3d.net/
Regardless, I wish all of those projects success and would still be glad if Godot could be one of the champions of open source game engines, perhaps as a viable and easy to use alternative to something like Unity for those who want that sort of thing, even in the professional development space eventually!
- Can I use any Java 3D or jMonkey with Codebase one?

I can't think about another video game using Java. I mean, there WILL be more but i haven't saw them.
It is, or at least was, efficient. Java has a great game engine called https://jmonkeyengine.org/ that at the time could compete with Unity, not sure the status now. And LWJGL, the lower layer for ooengl, was quite nice to use and it is efficient to go that low level if you plan to do a game that does not fit the stereotypes in such game engines, as you will find yourself fighting the engine more than the actual game.
