I compared output for JDK API docs before and after this patch, they are bit-for-bit identical. This is what I would have expected, since `HtmlTree.add(Content)` is pretty much the only relevant place where `Content.isValid()` is invoked (apart from some peripheral writers, and as of JDK-8267219, `ContentBuilder.isValid()`). > I agree with Jon on that this change should be tested thoroughly.
