To exercise the benchmarks, run the following in a terminal:
mvn verify -P run-benchmarks
The forking required by JMH does not work when running the benchmarks using the Maven plugin in IntelliJ IDEA 2019.2.4.
A note about creating a JPMS (Java) module for the benchmarks.
This does not work because there is a package clash between jmh-core and
jmh-generator-annprocess which prevents them being loaded as automatic modules
at the same time. jmh-core has a package org.openjdk.jmh.generators.core
which clashes with org.openjdk.jmh.generators in jmh-generator-annprocess.
