HtmlDocletWriter.getPreviewNotes analyzes classes and their members, to see if some are using aspects that are under preview. When looking at the members, it uses utils.isIncluded on the member, and that eventually gets here. And if the member is a RECORD_COMPONENT, it would fail here. But we can avoid asking for RECORD_COMPONENTS, if needed.
