Scala & sbt Docker images Why another Docker images for Scala and sbt? The reasons I make another Scala and sbt Docker images: It will be great to use JVM that passed TCK/JCK. AdoptedOpenJDK's OpenJ9 was just passed TCK/JCK. We should give it a try. Which JVM do those images use? Azul Zulu Eclipse OpenJ9 Available Docker image tags Azul Zulu Java 7 Java 8 AdoptedOpenJDK OpenJ9 Java 8 The base images I used azul/zulu-openjdk adoptopenjdk/openjdk8-openj9
