If a bundle undergoes a refresh while ipojo is still initializing components, a deadlock can happen. The issue is that if ipojo is attempting to register a service, it will be doing it while synchronizing on the InstanceCreator instance. It will then try to register a service which requires the framework's global lock.
If a refresh is happening in another thread, the refresh will be holding the framework's global lock, which will then call IPOJO's extender, which then attempts to call a method on InstanceCreator, hence leading to the deadlock.
