Yes, if I understand you correctly. Are you talking about the scope when you declare the aspect? Although, this scope is quite course-grained. PER_VM - all share the same semaphore PER_CLASS - all instances of a class share the same semaphore PER_INSTANCE - each instance has the same semaphore etc. It might be worth allowing for an extra attribute on the annotations to declare a "group" or something to choose the semaphores?
