JLink (JEP 282) does the first part and was released with Java9 (6 years ago), the native compilation stuff is a product of GraalVM. Binaries are reasonably small but it depends of course on what your app is doing. There is a whole ecosystem of web frameworks that's being built on that (quarkus.io, micronaut) and IIRC you can build a simple REST API that ships as a <20MB container.
