That's strange, as the code compile for me, and I receive error if I comment
the super(source);

cannot find symbol
 symbol : constructor event object
 location class.java.util.EventObject.

Looking to javadoc for EventObject I see the only constructor available for
EventObject is

  *Constructor Summary*
*EventObject<http://127.0.0.1:8082/resource/jar%3Afile%3A/D%3A/Javapassion/jdk-6u21-docs.zip%21/docs/api/java/util/EventObject.html#EventObject(java.lang.Object)>
*(Object<http://127.0.0.1:8082/resource/jar%3Afile%3A/D%3A/Javapassion/jdk-6u21-docs.zip%21/docs/api/java/lang/Object.html>
 source)
          Constructs a prototypical Event.

So, my understanding is that, extending EventObject, I need to initialize
it, so I must call super(source);

Can you check to ensuere in the code you are testing the class is really
declared in this way :

public class MyEvent extends EventObject {
