Give super powers to Java with WebAssembly
summary
Claims that Java can host real WASM plugins via Extism runtime with Java bindings and shows a working Vert-x app loading modules written in Rust Go and Zig. Demo uses WASI-style host functions for config HTTPS and request I O, a registry that loads modules at runtime, and a container image built once so modules swap in without rebuilding. Code examples compile to WASM, load from Java, and the demos complete successfully.
