+/**
+ *Makes sure that the ProgressObjectImpl class functions correctly.
+ *<p>
+ *In particular, bug 4977764 reported that the ProgressObjectImpl class was susceptible to
+ *concurrent update failures in the vector that holds registered progress listeners. The
+ *fireProgressEvent method worked with the vector of listeners itself rather than a clone of the vector.
+ *One of the listeners unregistered itself from the progress object, so when the iterator tried to
+ *get the next element it detected the concurrent update. So, the progress object now clones the vector
+ *temporarily in fireProgressEvent and iterates through the clone.
