All we need to do is monitor for scenarios where refresh has to propagate to other bundles or to the application as a whole. So, it's not so much that we have a ClassLoader that updates when bundles come up, but rather we get new ClassLoaders when bundles are replaced, and updates cascade as needed. Rob Colin,

So your ClassLoader does actually dynamically update as bundles are added and removed? Have you had any issues with removing or replacing bundles? We had some tricky issues around these sorts of issues with our persistence layer, do you just force a refresh in those circumstances? Hehe, I imagine so.

We are in the process of tracking them all down, but I doubt that they will prove to be insurmountable :) Rob Colin,

One question, does your auto-importing ClassLoader update dynamically as bundles are registered and deregistered? Have you seen any issues around this? I can imagine a lot of memory leak scenarios with classes being endlessly loaded by this ClassLoader in a long-running server scenario. Interesting to see how you're solving some of these problems.
