Thanks Dane for once again pushing the topic on Java language support. In terms of project maintenance and long term growth, I am happy with this change.
Regarding the usage of `--add-opens`, it would still be okay, given the fact that we provided that option either way. But in future, I think we should figure out a way to do this better. Although as you suggested, it would be best to gather feedback from the community, specifically that we have already done a minimum version upgrade very recently. Also, it would be better to do this around v20 or v21 if we agree to move forward. The reason is it would at least give enough time for some users to get ready for a change. Again this may require consensus in the community. Also we can take another consensus from the github dependabot PRs, it provides a hint on how much technical burden and vulnerabilities we have to keep up when we don't upgrade the minimal supported Java version. I think we had a good experience in gathering those details for Java 8 [1] (citing once more). +1 for this proposed change.
