After spending some time breaking my head on editing manifest (see how to config manifest with maven) and all those java configurations, I've found how it works:

To grant allPermissions with java 1.7+ you need to edit java.policy file.

Use the policytool to do that. At prompt command line:

policytool

see Oracle tutorial: http://docs.oracle.com/javase/tutorial/security/tour1/wstep2.html

Open the right policy file where your browser vm is executing. For me its in:

C:\Program Files (x86)\Java\jre7\lib\security\java.policy

Should load some CodeBase list. Click on it for edit or:

Add Entry

Leave CodBase blank for every location where code is running but you can put localhost or your stite if you want and signedBy blank for non signed jars/applets. Click Add Permission, then choose AllPermissions
I have CodeBase and it java.security.AllPermission

Then save! java.policy and should get sucess message.

Done you can run non signed applet and acess disk files.
