When the command runs, we'll have the output in the console, which shows the VM options:

# JMH 1.18 (released 134 days ago)
# VM version: JDK 1.8.0_131, VM 25.131-b11
# VM invoker: /usr/lib/jvm/java-8-oracle/jre/bin/java
# VM options: -Xbootclasspath/a:some/jars
# Warmup: 10 iterations, 1 s each
# Measurement: 20 iterations, 1 s each
# Timeout: 10 min per iteration
# Threads: 1 thread, will synchronize iterations
# Benchmark mode: Average time, time/op
# Benchmark: dotty.tools.benchmarks.Worker.compile
