[JAVA] I tried to verify AdoptOpenJDK 11 (11.0.2) with Docker image
A bug in HTTP communication with Java 11 has been fixed in 11.0.2!
Communication is not possible due to the following error ... https://stackoverflow.com/questions/52016415/jdk-11-ssl-error-on-valid-certificate-working-in-previous-versions
Exception in thread “main” javax.net.ssl.SSLHandshakeException: extension (10) should not be presented in server_hello
Docker image
https://hub.docker.com/r/adoptopenjdk/openjdk11
Preparation
Dockerfile
FROM adoptopenjdk/openjdk11:latest
RUN mkdir /opt/app
COPY hoge.jar /opt/app
CMD ["java", "-jar", "/opt/app/hoge.jar"]
$ docker build -t japp .
$ docker run -it --rm japp
important point
It's silly, but ... You have to put hoge.jar in the Dockerfile hierarchy COPY failed: stat /var/lib/docker/tmp/docker-builderXXXXXXX/xxx no such file or directory I get an error like this.
result
This time, only the code that outputs the result of HTTP communication is written, so Communication success was confirmed by outputting a response to the console.
