But java bytecode itself is interpreted. For things like the web, you really want a language that can start executing immediately, so you really need to interpret, or have an agnostic bytecode.
I think it's a bit of a stretch to call the JVM an interpreter. Having said that, if you want to deliver Rust as bytecode, emscripten would seem to satisfy that usecase (though obviously that's not what the original author was talking about, and it doesn't work properly at the moment).
