There are also some advantages towards the tarball jar encapsulating multiple jar approach - some cloud platform Java buildpacks superbly optimize the deployment process by only sending the differential jars - sometimes just the differential classes - which makes deployment 2x-3x faster than Golang single big bang executable approaches. In our company which leverage both Java microservices and Golang microservices - the Java app deployment is much faster!
