OpenJDK 10/11
OpenJDK 10/11 is part of Ubuntu 18.04 LTS ("bionic"): https://packages.ubuntu.com/bionic/openjdk-11-jdk

I propose making OpenJDK 10/11 the default for this Docker base image (without changing its name).
It might break a lot of applications that still rely on private APIs (like sun.misc.Unsafe). I would suggest to publish a separate image for testing first, because the migration path might be non-trivial (or impossible if applications rely on unsupported libraries).
@aermakov-zalando yes, I think for migration purposes it makes sense to gradually release with a new name, but mid-term I would change the default (people can always pin their version to a known good Docker image tag).
@hjacobs will Java 11 be soon available? Any further plan if it will be the default or like suggested a separate image. Would like to start migration process as soon as possible. Can even create the necessary PR just need to know which direction is preferred.
Since Java 10 there, the JVM is aware of running in (Docker) containers. This is extremely useful for applications running on Kubernetes to not get OOMKilled every couple of minutes.
@lalib we don't actively work on it, if anybody wants to pick this up, feel free :smile:
@hjacobs I've opened a PR to add a JDK 11 build if you get a chance to review. I was hoping it would auto-trigger a build. Not sure if there is some other process for that 😕
@vadeg please look into our internal Zalando Developer Console and search for "jdk11", you will find a migration guide (which does not rely on this base Docker image anymore).
