The AspectJ matcher can be used for matching pointcuts independently of any AspectJ compilation or weaving steps. Most notably, this can be used by frameworks such as Spring AOP which utilise the @AspectJ pointcut syntax but implement aspect weaving in a way independent of AspectJ, e.g. using dynamic proxies.

There is a newer version: 1.9.22.1
