Hi Philippe!

Thank you very much, appending the aspectjrt.jar to the bootclasspath did indeed solve my problem!

I've also had a look at your research paper and I'll give it a proper read soon, since I'm doing possibly related research. The end-goal of my research is not exactly the JDK weaving; this is more like means to an end. But I'll definitely give the FERRARI framework a look.

Thanks again!

Hi!

It might be a classloader issue. I think I had similar issues in the past.
Have you tried to add aspectjrt.jar to the bootclasspath ?  Not sure there is
a good explanation for this, but it has solved some similar problems in the
past. The JDK classes are loaded by the system classloader and for some
reasons it may expect to find the CFlowCounter in the bootclasspath as well.
