It is a known weaver limitation (there is a bug report with full details).

You will need to add something like: '&& execution(* *(..))' to your pointcut to select method execution join points (and avoid selecting handler join points). In any case, your description specifies that you need to profile method execution so the change will match that while fixing the problem you see.

Objet : [aspectj-users] LTW+cflow+after/arround advice

 

Hi,

I want to catch duration of a method and the duration of the methods in the cflow scope of this method.

I use LTW weaving.

 

I try it with two kinds of  strategiy for the advice :

- around ( Aspect in issingleton PerClause)

- before+after ( Aspect in percflow PerClause)

 

The implementation of the aspect in aop.xml looks like this:

<concrete-aspect name="iep.perf.aspects.abstractAspects.DurationSimpleMethodWithParentPercflow"

                  extends="iep.perf.aspects.abstractAspects.AbstractDurationSimpleMethodWithParentPercflow" >

                  <pointcut name="methods"

                        _expression_="

                        cflow(

                        call(public * pcm.metier.refarticles.CmRefArticles.offreORTHorsCatalogue(..))

                        || call (public * pcm.metier.refarticles.CmRefArticles.offreORTStandard(..))

                        || call (public * pcm.metier.commande.CmRechercheBCR.lister(..))

                        || call (public * pcm.metier.codeadv.CodeADV.searchByCodeADV(..))

                        || call (public * pcm.metier.refarticles.CmRefArticles.listerModelesHorsCatal(..))

                        )" />

            </concrete-aspect>

 

 

And I got this very explicit error:

 

[AppClassLoader@1554b97] warning at iep/perf/aspects/abstractAspects/E:\eclipse\workspace\perfStats\src\iep\perf\aspects\abstractAspects\AbstractDurationSimpleMethodWithParentPercflow.aj:47::0 Only before advice is supported on handler join points (compiler limitation)

[AppClassLoader@1554b97] warning at org/objectweb/jonas/server/Bootstrap.java:98::0 Only before advice is supported on handler join points (compiler limitation)

[AppClassLoader@1554b97] warning at iep/perf/aspects/abstractAspects/E:\eclipse\workspace\perfStats\src\iep\perf\aspects\abstractAspects\AbstractDurationSimpleMethodWithParentPercflow.aj:47::0 Only before advice is supported on handler join points (compiler limitation)

[AppClassLoader@1554b97] warning at org/objectweb/jonas/server/Bootstrap.java:108::0 Only before advice is supported on handler join points (compiler limitation)

 

In line 47 of the aspect, I define an after pointcut.

 

I got the same error with the around advice.

 

If my understanding is correct, it means that only before pointcut supports cflow pointcut. Am I right?

 

With LTW, is there a workaround to track duration of method and duration of methods in the cfow scope of the first method?
