Forward javacOptions to JMH

[Quafadas]

I believe this to be a solution for #3576 . However, I'm unclear how I could effectively test it. Feedback welcomed.

@Quafadas I think manual testing is fine for this. Presumably you are able to reproduce the original reported issue, and can use installLocalCache to see if your PR fixes it?

[Quafadas]

The original issue I could reproduce easily. In the issue I left a comment which was a workaround, where I copy pasted overrode the method in my local build, and that fixed the issue.

I’m afraid I don’t understand the installLocalCache part of your comment, apologies?

Oh I meant that you could use it for manual testing: it generates a local mill binary with all thee stuff publishLocaled for you to try out. But if the override works in your local build, I think that's enough confidence for me
