It looks like you’re blocking the event dispatch thread(EDT). SwingWorker would be a better choice, but this example implements Runnable.
Addendum: You might look at this project for an example of MVC architecture. It also shows how to construct a Mac OS application bundle without using JAR Bundler. More on MVC may be found here.
As an aside, this example shows one approach to auto-scrolling a JTable. Click on the thumb to suspend scrolling; release to resume.
Addendum: Your application lags for 10 seconds on startup. As this is the exact time for which the Controller sleeps, it’s surely sleeping on the EDT. An sscce would be dispositive. Instead, do the work on another thread and update the model on the EDT. SwingWorker has a process() method that does so automatically, or you can use invokeLater() as shown below. Until your application is correctly synchronized, there’s little hope of getting Apple events to work.
Addendum: You can invoke isDispatchThread() in the Controller to check. The project cited includes a .dmg with a Mac application and an ant file that builds the bundle in situ via target dist2.
Addendum: See also the alternate approaches shown here.
