Benjamin,
Try this instead:
package test1;
abstract privileged aspect Aspect
{
before(Test self) : execution(* Test.sayHello())
&& this(self) && !cflow(within(Aspect) && adviceexecution
())
{
System.out.println("before:sayHello");
self.sayHello();
}
}
You are experiencing a variation on the problem of advising yourself.
Sometimes you get NoAspectBoundExeption. Your within(Aspect) pointcut
matches more join points that you need including static initialization.

[aspectj-users] Abstract aspect and !cflow(within) results in
ExceptionInInitializerError
Hello,
with the program given below, I get the exception:
Exception in thread "main" java.lang.ExceptionInInitializerError
at test1.Test.sayHello(Test.java:7)
at test1.Test.main(Test.java:13)
Caused by: java.lang.NullPointerException
at test1.Aspect.<clinit>(Aspect.aj:1)
... 2 more
Making "Aspect" concrete and removing "ExtendedAspect" makes everything
work
fine.
This appears to be a bug in ajc. Do you agree?
Thanks,
Benjamin
