Update the documentation to include the advice of using within() together with lone kinded pointcuts [SPR-6123]

[spring-projects-issues]

Andrei Stefan opened SPR-6123 and commented

A large number of ShadowMatchImpls objects are created and cached in case a simple execution() pointcut is used. In case this pointcut is combined with a within() clause, as pointed out here: http://dev.eclipse.org/mhonarc/lists/aspectj-users/msg10969.html, the problem goes away, since the method matching in beans is stricter.

It would be good to reflect this advice in the Spring documentation, as well.

Fixed. Added to the end of the AOP section 7.2 'Declaring a pointcut', a new short section called 'Writing good pointcuts'.

Similar advice now also online with AspectJ at the end of this page: http://eclipse.org/aspectj/doc/released/progguide/language-joinPoints.html
