Component used: Macrobenchmark 1.2.0-SNAPSHOT

Sometimes I get an exception probably that some metrics didn't provide the same results.

java.lang.IllegalArgumentException: At least one result is necessary.

I think the minimal thing to improve is at least add information about the metric so you can investigate more why this happenned?

- require(size >= 1) { "At least one result is necessary." }
+ require(size >= 1) { "At least one result for $name is necessary." }
