Version 0.1.4 doesn't work with Java 9
It prints the following message:
# Run progress: 0.00% complete, ETA 00:15:50
# Fork: 1 of 1
# Preparing profilers: FlightRecordingProfiler
# Profilers consume stderr from target VM, use -v EXTRA to copy to console
<forked VM failed with exit code 1>
<stdout last='20 lines'>
[0,105s][error][arguments] -XX:FlightRecorderOptions=settings=... has been removed. Use -XX:StartFlightRecording=settings=... instead.
Error occurred during initialization of VM
Failed to start tracing backend.

Give JFR recording file meaningful names
Got around to playing with this finally. Very nice!
The produced recording files should be named in a way that makes it easy to match them to the appropriate benchmark.
Release version 0.1.4
Now that we #10 is merged, could you please release version 0.1.4 to Maven central?
Thanks,
Leo.
java.lang.AbstractMethodError
I'm getting this error after running a JMH benchmark with -prof jfr:
# Processing profiler results: jfr Exception in thread "main" java.lang.AbstractMethodError:
profilers.FlightRecordingProfiler.afterTrial(Lorg/openjdk/jmh/results/BenchmarkResult;JLjava

The full listing of my JMH command and results are here:

Parameter IDs should be sanitized before use in file names
I had the following in a benchmark:
@Param("foo/bar")
var path: String = nullThis led to an IO error in FlightRecordingProfiler writing the .jfr file. I'd suggest to replaceAll("/", "_") in the ID to avoid this problem.
Publish to Maven Central / JCenter
Great work!
Maven artifacts contains an empty BanchmarkList
This sort of creates issues when creating a fat jar to run on a test rig. Depending on the package name.
It can be excluded but would be better to not have an empty BenchmarkList in the published artifact.
Update and test JMH 1.2 (with classpath discovered profilers)
