1. Basically, every time you use a Swing component or a model of a Swing component, it must be done in the EDT. If you don't, no exception will be raised. It could work, but it could also not work, have erratic behavior, corrupted data, etc.
2. Every Swing event listener is called in the EDT. Basically, except the main method, every line of code of a Swing application is executed in the EDT by default, unless you explicitely start a thread, use a SwingWorker, or something like that.
3. yes.
4. Tasks submitted to SwingUtilities.invokeLater() are executed in the same order as the order they were submitted.
5. Internally, it uses SwingUtilities.invokeLater() or a similar method. The FutureTask doesn't have anything to do with Swing. It's the SwingWorker that ensures that its done method is executed in the EDT. The doneEDT() method has the following comment: Invokes done on the EDT.
