The automatic installation of Tool JDK 10 failed today for us with a 404. It seems Oracle JDK 10 not available anymore at all. And Java 11 cannot be used in production due to new licences. No JDK 11 is available in Jenkins java.sun.com JDK Tool installer.

https://www.oracle.com/technetwork/java/javase/downloads/jdk11-downloads-5066655.html

I guess the tool installer should be changed to use http://openjdk.java.net/projects/jdk/11/ (downloaded from http://jdk.java.net/11/).

Acceptance criteria

• a JDK 11 is proposed as download
• ideally, see if we can still propose JDK10,
• and JDK12
