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/

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:

https://github.com/dylibso/chicory/issues/1296

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.

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

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.

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