The javadoc for javax.swing.Timer points to a link on how to use timers in the Swing Connection that no longer exist.

Either the link should be updated to the current link (if it exist) or removed.
ACTUAL -
The link points to http://java.sun.com/products/jfc/tsc/articles/timer/ which redirect to http://www.oracle.com/technetwork/java/index.html
