Wraps a bit of Swing pain.

With lombok:

 class SwingApp {
        private final JFrame frame = new JFrame();
 
        @SwingInvokeAndWait
        void start() throws Exception {
                frame.setTitle("SwingApp");
                frame.setVisible(true);
        }
 }
 

 class SwingApp {
        private final JFrame frame = new JFrame();
 
        void start() throws Exception {
                final java.lang.Runnable $startRunnable = new java.lang.Runnable() {
                        public void run() {
                                frame.setTitle("SwingApp");
                                frame.setVisible(true);
                        }
                };
                if (java.awt.EventQueue.isDispatchThread()) {
