Remote Applet debugging under Java 1.7 update 21

With the latest update, I can no longer seem to debug applets. I currently have the parameters -agentlib:jdwp=transport=dt_socket,address=localhost:1234,server=y,suspend=n set in control panel, but nothing starts listening on startup of my applet on the port 1234. Update 17 was fine with this. Is this a security setting I need to change (I've tried lowering everything I can think of)? Manifest change (currently have Trusted-Library: true along with being signed)? Or has Oracle just broken this without testing it?

Also on that note... I'm running Windows Server 2008R2
