Create Docker Image For JRE FROM scratch

I am trying to create a image using JRE without any OS. I tried this Dockerfile which does not work.

    FROM openjdk:11.0.1-jdk-oraclelinux7 as JDK
    RUN jlink --no-header-files --no-man-pages --add-modules java.base,java.desktop,java.logging,java.sql --output /jre

    FROM scratch
    #FROM oraclelinux:7-slim
    COPY --from=JDK /jre /jre
    ARG JAR_FILE
    COPY ${JAR_FILE} /app.jar
    CMD ["/jre/bin/java", "-jar", "/app.jar"]

I am getting following error:

    standard_init_linux.go:190: exec user process caused "no such file or directory"

If I replace scratch with oraclelinux, it works fine. Any clue why I cannot use scratch. The reason to use scratch is to reduce the size of the image.

Any help is appreciated.

The hotspot sources do not currently support statically linking. See http://mail.openjdk.java.net/pipermail/hotspot-dev/2013-September/010810.html for more info.
