Hi, I am definitely in favor of switching to jdk11 by default, it's really time to move forward. We have been using it on the Jenkins infrastructure project for almost a year now without major issues but we also had to fine-tune the java configuration for java 11.
That remains a major change with potential breaking changes, so I would announce it enough in advance so people can already switch to jdk11, and keep the java8 for several stable releases with a deprecation warning.
