[Springframework-developer] reloading/hot swapping of beans

[Colin S. <col...@ex...>]

This is only of use in certain scenarios, but we should maybe examine 
the possibilities w/regards to unloading and reloading of beans. Both 
HiveMind and now Pico
  http://www.picocontainer.org/hotswapping.html
allow reloading of a bean/component returned from the container, due to 
the fact they they automatically introduce a dynamic proxy for the 
object returned form the container.

This has a slight performance impact, but is probably the easiest way to 
handle reloading. Now how much additional 
complexity/variability/breakage this could introduce is I think pretty 
hard to figure out, given the amount of stuff you can do now with things 
like the BeanPostProcessor which can affect the lifecycle of a bunch of 
things in the container.
