We are using AspectJ(1.6.12) for weaving a third party library class (SpringBeanELResolver). We enable LTW using <context:load-time-weaver/>
, and our aspect uses AspectJ annotation configuration. Everything works fine on jetty with full list of classes seen on debug output of Aspectj. As documented on Spring, we don't use -javaagent since it is not needed on Websphere platform.
On Websphere 8, we see logs that Spring correctly initializes WebSphereLoadTimeWeaver
, and Aspectj is correcly initalized. But we see just a portion of classes on debug output of aspectj. SpringBeanELResolver also is not included for weaving. As a result, our class is not weaved.
We can weave classes listed on debug output, e.g. our classes..
We configure Classloading policy to PARENT_LAST.
Here are some logs and configurations:
Websphere SystemErr (most of the 3rd party classes are not seen here including SpringBeanELResolver)

I think that CompoundClassLoader might have issues loading all 3rd party libraries in WEB-INF/lib or, it is something between Aspectj and CompoundClassLoader...
