This is reproducible, but only happens to a single bean in my context. Other beans with the same aspects applied work fine. This screenshot shows the contents of the stack right before the call that causes the exception, I hope that helps. If not, please let me know how I can assist.

Hi Jürgen, that of course could be related to my workaround from https://bugs.eclipse.org/bugs/show_bug.cgi?id=306915

I've simply added a (runtimeTest != null) guard to all those checks in RuntimeTestWalker... Not sure it'll solve the underlying problem but it at least avoids unpleasant NPEs.
