All is well.  Please get a fresh checkout from CVS and retry.

One major thing to watch out for:

make sure you do not have conflicing JARs in your classpath.

If you have an old version of Event in your WEB-INF/lib directory
along with the new one, there is a good chance you are not seeing
a new abstract method because the old class is being loaded.

Please double-check your JARs
