-          The Kotlin configuration here is a bit unusual. JetBrains recommends
-          <https://kotlinlang.org/docs/maven.html#compile-kotlin-and-java-sources>
-          a fairly invasive reconfiguration of the maven-compiler-plugin (which compiles Java)
-          in order to ensure that the Kotlin compiler can run first. In our case, we have just
-          one Kotlin file that a test in Java accesses. So, even though it is in src/test/java,
-          we compile it in the `compile` goal, which means it is available to the Java test sources
-          when they are compiled in the `default-testCompile` goal.

-          Currently if you want to use JDK ≥ 16 then you must set
-          JAVA_TOOL_OPTIONS=__illegal-access=permit
-          except the two underscores should be dashes (which XML comments won't allow us to write).
-          This is a bug that will presumably be fixed in a forthcoming version.
