What Hacker News says

GraalVM native-image is not a listed option, but I regularly use it to produce binaries that are competitive with (often better than) Go in terms of size and (start time) perf. A Clojure tool that parses, traverses and processes JSON (caro, see below) worked out to 3.2MB. I'm sure C and Rust can do better, but it's not bad compared to a JVM, and it's an order of magnitude better than the best option in the article. It's also small enough that while comparisons like "that's three floppies!" are interesting historical perspective, you can't reasonably complain about having a 3 MB binary in ~/.local/bin. Examples: https://github.com/latacora/wernicke/releases https://github.com/latacora/recidiffist-cli/releases https://github.com/latacora/caro/releases It mostly works out of the box. My biggest frustration is that you can't easily link in dy

namic libraries, which makes it a little annoying to do e.g. EC TLS with a single binary. (Go would have a similar problem but sidestepped it by reimplementing most of it natively.) Second biggest frustration: it is not a fast compiler. You're definitely doing development on the JVM (I use Graal as my default JVM now) and a "production build" afterwards with native-image.
In Really Small Java Apps
I'm not GP, but we have done several native Clojure CLI apps with Graal: https://github.com/latacora/wernicke https://github.com/latacora/recidiffist-cli https://github.com/latacora/caro As well as several internal tools. It mostly works fine. Graal is actually the default JDK on my development machine. If there's one thing I'd fix, it's the ability to bake dylibs into the single binaries. E.g. if you want good elliptic curve TLS, you need sunec.so/dylib/dll, and part of the point for native-image for us is the ability to ship a single binary.
