Versuchen Sie es mit Java 9

FROM java:9
COPY . /usr/src/myapp
WORKDIR /usr/src/myapp
RUN javac Main.java
CMD ["java", "Main"]

import java.util.stream.Stream;

public class Main {
  static public void main(String[] args) {
    Stream.of(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)
      .takeWhile(i -> i < 5)
      .forEach(System.out::println);
  }
}

$ docker build -t my-java-app .
$ docker run -it --rm --name my-running-app my-java-app
