> This is occurring in the beforeafter example when using loadtime weaving.
> One thread loads a generated joinpoint class, and waits on the AspectManager lock to transform the class.
> Another thread uses the AspectManager lock to create a PER_VM aspect. At the moment of creating the aspect, this thread needs the class loader lock, held by the first thread.
