security - Can i deny access to a jvm class by configuring java.policy file?

Question

I wanted to add to my jdk6jrelibsecurityjava.policy file an interdiction to create some classes that are blacklisted by appengine. For example I want my local jvm to throw an exception when the application tries to instantiate javax.naming.NamingException.

It is possible?

I will try to explain my specific problem here. Google offers an service (GAE-google app engine) that has some limitations on what classes can be used. For example doesn't instantiate JNDI classes that are in javax.naming package. They also offer an testing server that can be used to tests this application on my machine, but this server allows such classes and can exacute the code. You find out that you used a blacklisted class only after you upload your application to google. I was thinking if such class blacklist enforcement couldn't be done on the development jvm. Else i'm thinking that this would be easy they might already provide such a policy file.
