Tested OS/Browser:
                        XP-Home(sp2)/IE6
                        win 2000 pro(sp4)/IE6/NS7.2
                        win ME/IE6

Tested build: j2re 1.6.0- build 27

Problem:
-------

Applet fails to load. java.lang.ClassCastException thrown.
The applet works fine on the same sysetm using Microsoft VM-Release 5.0.0.3810
It's a regression. Other Yahoo applets displayed the same issue:
Text Twist, Word Mojo Gold




Steps to reproduce:
------------------
1) Install j2re1.6.0-build 27 into the test system.
2) Go to http://games.yahoo.com
3) Click on "Super Bounce Out" under Super ARCADE GAMES section

With Sun VM (1.6.0-b27) the applet fails to load with the following exception
from the Java Console:
