I'm a big fan of Capsule, actually. My point was not that Java and the JVM ecosystem are terrible (I quite like them), but rather that there is a spectrum of size and complexity and that Go's static binaries seem to be on the simpler to build side of JARs and on the smaller side of JARs.

Also, I don't think there's much of a case to be made that bundling a JRE with your JAR is small, even though the tooling might be simple and it might resolve many deployment issues.
