| You should be able to get the current value if you use before advice. Of the top of my head (and hence with likely errors...):
before(MyClass object): set(* Class.foo) && this(object) && args(newValue) { System.out.println("Old: "+object.getFoo()); System.out.println("New: "+newValue); }
This assumes you have a "getFoo()" method. If so, be careful about advice on get(* Class.foo)! Alternatively, you could reference object.foo directly if foo is package private and the aspect is in the same package, etc.

I would like to be able to inspect the current value of a field in addition to the value that is being assigned to it during the application of my advice. I am using the set pointcut designator in my advice and I can determine the name of the field using thisJoinPoint.getSignature().getName(), but not the value.
This is for an automatic event mechanism where I need name, oldValue and newValue.
Is this even possible?
Thanks
