Renaissance Neo4jAnalytics is ~2x slower after JDK 8

I have been investigating adding more Renaissance JMH to dev-submit. It appears that org.renaissance.neo4j.JmhNeo4jAnalytics has gotten almost 2x slower after JDK 8, I am not sure it is just a compilation order problem.

In 17-b4 it spends a lot of time on some stub code.
I am running another dev-submit to see how it looks with -TieredCompilation.
