If I understand this thread correctly, you want to replace Avalon with a 
custom framework. I think that this is not a good idea. Moving from an 
obsolete framework to a custom framework seems like jumping out of the 
frying pan and into the fire. I think it would be better to use 
something that has traction in the larger Java community, like Guice or
