Endive: A JVM native WebAssembly runtime

Shameless plug: we solved the opposite problem, running any Java application in the browser via WebAssembly: https://labs.leaningtech.com/blog/cheerpj-4.3

And yes, it does run Minecraft as well :-) https://browsercraft.cheerpj.com/

Projects like this would be significantly funner and easier to make in Jdk25+(well technically 24+) because of the new Java classfile/bytecode API. It looks like Endive uses OW2 ASM, probably because this supports back to Jdk11. The new jdk API has a minimum target of Jdk17. OW2 ASM is significantly harder to use IMHO though.

What got me into this is I just finished a major release of Petrify (https://github.com/exabrial/petrify) that compiles ML Models to JVM Bytecode. It requires Jdk25 to do the compilation, but the compiled models can run on Jdk17+.

I'm looking for more side projects to use the classfile API on.

On the CNCF wasmCloud Community call this week we played with this: - a demonstration of Endive - implemented CNCF wasmCloud host - Integrated into Vert.x as an example

And discussed the roadmap.

This is a fork of Chicory, a bit more context of the relationship between the projects can be found here:

Lots of context for this project on the Bytecode Alliance blog: https://bytecodealliance.org/articles/endive-and-the-next-ch...

It will be really great if this becomes a second popular runtime with both GC and WASI component model support. Wasmtime being the only runtime with that combo is a bit concerning. Node supporting the component model will help a lot too.

		The component model is still in phase 1 (standardization is phase 5) and the Bytecode Alliance are its sponsors and the ones pushing it into the ecosystem with wasmtime.

Is this being handed over to the Bytecode Alliance or is this a hard fork and will diverge from Chicory? It isn't clear from the announcement but I suspect the former.

I guess we can come full circle and eventualy port it to Android Java.

		Yeah, this was the first thing that came to mind, how does this compare to the Truffle WASM implementation. The Graal Polyglot API is pretty incredible, we've been using it for a JavaScript/Python plugin system in a JVM app, and it's been amazing.

Finally we can run Kotlin/WASM on desktop! /s
