WebAssembly is quietly becoming the standard way to embed non-Java libraries inside JVM applications. Projects like SQLite4j, QuickJs4j, pglite4j, JRuby, and TrinoDB already ship Wasm-compiled native libraries inside regular JARs, eliminating JNI complexity and platform-specific binary matrices. The underlying runtime enabling this ecosystem is Chicory, a pure-Java Wasm runtime, which is now forking into Endive under the Bytecode Alliance. Endive will integrate the Redline compiler (using Cranelift) for native-speed execution on Java 25+, and plans support for WasmGC and the Component Model. The vision: compose JVM applications from libraries written in any language via WebAssembly, with no rewrites and no native binary management.
