I'm curious as to where 17 came from in the existing pipelines, but assuming there's a good reason why this now needs to be passed in I'm ok with it :-)

So the smoke test job is only created if it didn't already exist. Because the jdk build used to produce JDK17 (until a few months ago), the generated jobs were set with JDK_VERSION as jdk17.
