I just locally used this as a replacement to `centerdot` and regenerated the javadocs. The generated javadoc HTML looks the same like the screenshot in my previous comment.

My only concern here is that this notation isn't used previously in any of our APIs and since it's part of a "regular" (non mathemical) sentence, it might be hard to understand what it is. I think it is relatable when it's part of some larger mathematical formula/explanation.

I just did a quick search of `centerdot` in the JDK source to see if it's been used in any API documentation currently and didn't find any such cases. So I still think using `*` would be clearer.

Having said that, if there are no objections from Roger or any other reviewers, it's OK with me too.
