Re: [aspectj-users] LTW, javaagent, JUnit and ANT integration

[Alexandre Vasseur <avasseur@xxxxxxxxx>]

@target(..) allows to bind the annotation instance to some variable
that can be passed in as an argument to the advice.
target(..) allows the same but not for the annotation, just for the
target instance
If you don't use them to bind variables, there is indeed some overlap
as you describe.

In your code sample the annotation is on the interface, not on the
actual declaring type of the called method. Try to move / copy the
annotation (and remember method level annotation cannot be inherited
as described by Java 5).
