It is the perthis instantiation model that causes the marker interface to
get generated 'BehaviourInvokeTracing$ajcMightHaveAspect', and as a
generated interface it should be getting defined directly - is there
anything that could be preventing AspectJ dynamically defining classes on
the fly? (Funky class loader in the mix or some such?). Are you able to try
compile time weaving? (weave into the akka jar you are modifying).
Something like compile the scala and then:
ajc -inpath akkajar.jar -aspectpath mycompiledscalacode.jar -outjar
wovenakkajar.jar
and then use the wovenakkajar.jar?
