At the moment the GeneratedAOPProxyFactory will create a proxy if there are some introductions or if there are interface introductions, mixins, simplemetadata or instance level metadata | if (!params.getContainerCache().hasAspects() && !params.getContainerCache().requiresInstanceAdvisor()) | { | return params.getTarget(); | } | else | { | proxyClass = generateProxy(params); | } | IIRC the reason for this condition was that having an introductions, metadata etc would mean that we could match more pointcuts. However, at the time this check is done, an instance advisor will have been generated if the condition was met, so I think the check should be changed to only return a proxy if the instance advisor has more aspects than the class advisor? Something like the following (pseudo-code): | ContainerCache cache = params.getContainerCache(); | | if (!cache.hasAspects() || (cache.hasAspects() && cache.hasMoreAspectsForInstanceThanInClassContainer())) | { | return params.getTarget(); | } | else | { | proxyClass = generateProxy(params); | } | This would mean modifying the aop-mc-int tests under org.jboss.test.microcontainer.matrix.mc.test (and possibly some others) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4141314#...
