Hi,
In fact it turns out that destroyComponents destroys beans, services and references in the correct order.
If you want to fix this issue you need to use reference listeners and tidy up in the unbind method.

FYI, We've had a customer run into this problem and, in using this patch,
discover that it's still not safe to use injected service references in a
destroy-method. During application stop, the bundle that provided the
injected service may all ready have been stopped. Due to the possibility of
circular references between bundles, this is a hard problem. We could _try_
to stop bundles in reverse dependency order but I still don't think we'd
have a general solution.
