> The following needs reviewing across AS7: -
>  - On demand instantiation of PrivilegedActions where singletons would suffice (Consider frequency of calls, gc may be preferable).
>  - Use of AccessController even though there is no SecurityManager set.
>  - Code duplication, in every case I have seen so far the code is the same regardless of if PRIVILEGED or NON_PRIVILEGED
>  - Utility methods with visibility too high.
>  - In depth review of the other methods, i.e. if the first thing a public method does is set the class loader based on a parameter passed in it could be used badly - it may even be a justification for that method to NOT use a PrivilegedAction.
>  - Code that requires to be executed using a PrivilegedAction should also be double checked that it is not doing too much as the identity of the caller.
