Thank you for the review, Jon.

I'll look into that - ideally, we would have all those JDKs installed/available on GHA when running `jtreg`'s self-tests:

- Warning: JDK8HOME not set; some tests may not have been executed
- Warning: JDK9HOME not set; some tests may not have been executed
- Warning: JDK10HOME not set; some tests may not have been executed
- Warning: JDK14HOME not set; some tests may not have been executed
- Warning: JDK18HOME not set; some tests may not have been executed
