Re: [aspectj-users] Is this possible with AspectJ (or AOP in general)?

Hello Ernii,
As far as I know, it is not possible for AspectJ to do weaving in JDK
classes. From what you have described, I suppose what you are defining
in your pointcut is something like:
public pointcut myPointcut() :
execution(public void java.awt.Component+.paint(java.awt.Graphics));
before() :
myPointcut() {
...
}
The previous will try to do weaving on the callee code, i.e., on the
Swing class that, if belongs to the JDK, will not be weaved. You will
only have success for your own classes extending Swing ones or calls
to Swing methods that occur within your own project.
I hope this helps. Regards,

If you use "call" instead of "execution" in the pointcut definition,
AspectJ will advise all join points in your code that call the Swing
methods you care about. AspectJ can access your code, while licensing
restrictions prevent you from advising the JDK library, as another
respondent mentioned.
So, you still won't affect calls from within Swing to itself, but
hopefully you only really need to advise Swing calls from your own code.
