I don't see any other place to hold the information about callback - e.g. (2) in JBMICROCONT-165 - than the KernelController. I need something like Class --> CallbackItems. Since when a new bean is instantiated - its classes, interfaces are resolved - I don't want to go over all already installed beans and 'ask' them if they need this new bean. I have already hacked something in this direction, I can put it in after I have tests done. Or how/where do you see the point of integration of this Class --> CallbackItems mapping?
