granting temporary private access

[cbongior]

So, here is the situation:

Using reflection, I would like to take 2 objects and call the equals()
method on their private members. Now, clearly if the code executes
inside one of the objects in question, accessing private members is not
a problem. What I would like to do is have some sorta shared method
that can be executed on any given object. Obviously though, if I do
something like this:

MyTestingObject.testEqual(this,otherObj);

is gauranteed to throw an IllegalAccessException since MyTestingObject
has no access to the private member of any other class.

So, What I had thought of was either temporarily granting said privs
through the SecurityManager/SecurityPermission objects, or having some
sorta Interface/Abstract attack at this problem.

Essentially, I would like to automate a deep compare between objects
without having to manually programming equals() as the equals() methods
of 10 member variables. This stems directly from my desire to unit test
an XML serializer

Maybe someone has an even better idea. Maybe assume equals() on bean
properties? Maybe I have been smoking way too much java.

method.setAccessible(true);

Assuming calling class loaded from the same class loader or no security.
