This is a follow up issue for fix of JDK-8026002. To reproduce install 7u51 nightly from http://rehudson.us.oracle.com/hudsonws/7u_cpu_deploy/bundles/windows-i586/b255-2013-11-04_313/jre-7u51-ea-bin-b255-windows-i586-04_nov_2013.exe
open http://oklahoma.us.oracle.com/www/tests/1.7.0_51/8026002/applet67.html from JDK-8026002 manual test page. To pass stricter restriction introduced in 7u51 slider setting needs to be Medium.
If you can see ClassNotFound excetpion(as shown in attachment 7u51.png) get thrown the issue is reproduced.
Although the ExitExcetion found in 7u45(as in attachment 7u45.jpg) is gone. The applet still can not load.
