I can't seem to figure out how to refresh my serverstatusdialog with a message that says shutting down in 15 seconds and then sleeping 15 and doing a system.exit(-1).
Basically my SSD has a shutdown action called when shutdown is pressed. This action create a confirm dialog with the ok of the confirm i unbind the rmi server, set a flag to prevent more requests, and then set the text value of the textfield on the SSD to "shutting down delaying 15 seconds" and finally Thread.sleep(15000).
What happens is the SSD freezes and does not update with the text, 15 seconds passes and the application quits.
Don't use sleep. The best way to schedule an event is to use a timer. If you are in a Swing GUI, you can use the javax.swing.Timer class, which is much easier to use than the java.util.Timer. The Swing timer causes an event to be fired when the time value expires.
