This doesn't seem to work. It compiles, bit this pointcut finds nothing.

I have one superclass "SuperClass" and a few classes extending from that 
superclass "ClassA", "ClassB", and so on.

In my application I never construct a SuperClass, I only have

ClassA a = new ClassA ();
ClassB b = new ClassB ();
...
so I never have (for example)
SuperClass something = new ClassA ();

If I write this:

pointcut findConstructors () : call (SuperClass+.new(..));

after () : findConstructors () {
	//do something
}

Everything works fine (the after advices is executed for every new 
instance of ClassA, ClassB ...). But in that after advice I want to do 
something with the object just constructed (of type ClassA, ClassB, ...).

Your suggestion is:

pointcut findConstructors(SuperClass superclass):
  	call(SuperClass+.new(..)) && target(superclass);

with this advice:

after (SuperClass obj) : findConstructors (obj) {
	//do something with obj (type SuperClass, but I will cast it)
}

That does compile, but it doesn't do anything. The after advice never gets 
executed. My IDE (eclipse) also indicates that that is the case.

Am I missing something?
