Richard S. Hall commented on FELIX-3003:
----------------------------------------
Well, candidates should not be null at this point, so it is difficult for me to
diagnose without being able to reproduce. I'd really like to look into this
issue, since I've heard about it once before, but I've never been able to
reproduce it. I don't need your specific bundles if you can create simple
example bundles that recreate the situation. I know nothing about Karaf,
Spring, etc., so I need a set of steps to avoid having to spend a lot of time
trying to remotely duplicate the scenario.
