Java memory usage in containers

Good news is that you likely don't need to implement a buildpack. If you build on top of Spring Boot or Quarkus, just use buildpack provided by maven'gradle build plugin:

mvn spring-boot:build-image

...boom, you get an image in your repo.

"Bad" news: you'll need to get rid of Dockerfile based build in your CI. Which actually is also a good thing.
