Update (Jun 20, 2025). This post was originally published at JVM Advent. And here we are again. For the third time in a row, we are back to the Java Advent, eager to discover what’s new with WebAssembly from a Java developer perspective. Incidentally, since, as you know, I have a favorite topic (after programming languages and compilers, of course), it is also the third time in a row I have worked at a different company.
