Hmmm, I think the error is caused because profiler supported check now passes when running in CI, whereas in the past this tests didn't attempt to run.

Although you cannot see the `Profiler is not supported or cannot be enabled, skipping test` message in successful JMH CI runs (e.g. [here](https://github.com/galderz/jmh/actions/runs/9320525801/job/25657504861)), you can see that the test runs in `0.218 sec` and so it must be passing because it sees the profiler is not supported.

With my change, it seems now the test thinks the profiler is supported, but then no secondary results are obtained.

I'm unsure how to deal with this yet.
