If you can encode your request processing patterns in statically sized types, then you can get the same high-level memory allocation behavior on both platforms. Arguably Rust makes this a bit easier. (Though I have no idea how much of the concepts of mechanical sympathy made it to mainstream Java.)

If you have some kind of super vague complicated patchwork of plugins that all contribute to processing, then the JVM seems to be the more convenient choice.
