JSR 223 in 2025

JSR 223 is a powerful specification designed to unify how Java interacts with scripting and polyglot engines. However, it was conceived many years ago, targeting early cross-language concerns. Today’s needs have evolved and we require a modern, expressive, simple, and shared API for accessing polyglot engines from Java.

Current shortcomings

Although widely implemented, JSR 223’s usefulness is hampered by optional APIs like Compilable and Invocable. To use them, developers must resort to unsafe casting, which creates leaky abstractions.

Title: WASM in the Enterprise: Secure, Portable, and Ready for Business

Speaker: Andrea Peruffo

Abstract: WebAssembly (WASM) is emerging as a powerful tool beyond its browser origins, enabling safer, more flexible, and more efficient execution across a wide range of enterprise applications.

In this session, we’ll take a hands-on look at real-world use cases, including:

    // starts, ends but does nothing, need to dig down!
    // TODO: note to self:
    // try to run this example first:

    @Test
    @Timeout(value = 30, unit = MINUTES)
    @Disabled
    public void runProtoc() throws Exception {
        var store = new Store();

- perf: how to run JMH and how to access CI results in Docs (move from folder)
- module system -> Edoardo TODO
- `aot` Readme in docs
- note design document of AOT compiler
- `WASMModule` rename as Module clash with `java.lang.Module`
- `ConstantEvaluator` -> use `long` instead of `Value`
- `CtrlFrame` -> verify how to minimize the data -structure -> e.g. use only one int for start/end (they should be mutually exclusive)
- `MemoryLimits` -> Instance with Memory factory
- re-use `FunctionType` -> verify usages around
- `Imports` mapping -> namespace + name is not part of the object but a pre-processsor does the mapping -> Instance doesn't treat differently "Imports" at all
