I am no JavaFX expert, but it has Views (for example, TreeView) whose "Items" are aware of a root generic type: for example, TreeView#setRoot(TreeItem<T>)... If the viewer input has no base class for all of its elements, then the API user would have to use Object again. I wonder how the JavaFX devs/community solved this issue...
