public abstract class SwingWorker
extends Object

Utility class based on the javax.swing.SwingWorker. SwingWorker is an abstract class that you subclass to perform GUI-related work in a dedicated thread. In addition to the original SwingWorker this class takes care of exceptions occured during the execution of the separate thread. It would call a catchException() method in the Swing thread if an exception occurs.
