I stepped on this problem too and couldn't find a solution for this.

Thankfully, JMH is extensible! My work around was to write an own profiler 
implementation to add arbitrary results to the benchmark. It is here:

https://github.com/cache2k/cache2k-benchmark/blob/master/jmh-suite/src/main/java/org/cache2k/benchmark/jmh/MiscResultRecorderProfiler.java

It needs to be enabled with:
-prof org.cache2k.benchmark.jmh.MiscResultRecorderProfiler

Cheers,

Jens
