enable unit tests with JDK11 (#8400)

* enable unit tests with JDK11

This enables unit tests with openjdk11, splitting up the build into
stages to have it fail faster

The integration test docker image still uses openjdk8, so there is
little reason to run those tests with JDK11 yet

* remove stages
