The title of this submission is "Show HN: 300k lines of Java UI code running native in browser at desktop speed," not "Show HN: page layout and report designer." The criticism is that this particular method of making Java UI code run in the browser, which is being shown to HN because it's presumably interesting to other people with large amounts of Java code as part of different applications, is inaccessible - not that the page layout and report designer is inaccessible.
