Thanks for the answer Alexander, I think what I am looking for should be achievable - at least judging from the code generated for the advice.
A reference to the instance of the Aspect is available in the call site of the isActive() method. So that means to me that 1. isActive() can be an instance method ( I admit there are use-cases where it must be static ) 2. when if() accepts an argument with a type of the Aspect type ( e.g. isActive(FooAspect aspect)) - instance of the Aspect can be resolved.
