You are not doing anything wrong: the @State dependencies should work as you would expect: all
states that are coming as arguments should have their helper methods executed. Except that there is
a JMH bug: it first runs all the helpers for Scope.Thread in DAG order, and then runs all the
helpers for Scope.{Benchmark|Iteration} in DAG order, which obviously breaks this assumption.

Let me handle this.
