Java has been one of the most popular programming languages for decades and remains the go-to language for many enterprises. Other JVM-based languages such as Kotlin, Scala, and Clojure have gained large and loyal followings, boosted by easy interoperability with the vast body of Java libraries and frameworks. There are already a number of options for translating Java bytecode into WebAssembly for use in browsers, including Bytecoder, TeaVM, JWebAssembly, and CheerpJ. However, none of these were suitable for cloud-based workloads until recently. This presentation will describe how to use TeaVM to build WASI-compatible WebAssembly modules from Java, Kotlin, and any other language that compiles to Java bytecode. It will also discuss some of the advantages of doing so versus using a traditional JVM, including faster startup time, broader language interoperability, and improved isolation of untrusted code.
