I collected a compile log for the jmh renaissance like this:

java -XX:+UnlockDiagnosticVMOptions -XX:+LogCompilation -XX:LogFile=ren.log -jar renaissance-jmh-assembly-0.11.0.jar -f 0 -wi 8 -i 8

It failed to process it apparently on Dotty:

java -ea -jar target/LogCompilation-1.0-SNAPSHOT.jar -i -t ren.log

and got
