> When debugging, it looks like that the array of HandlerDescription does contain the correct number of element (4) but the element with index 2 is NULL. So the HandlerDescription is missing for org.apache.felix.ipojo.handlers.event:subscriber handler. However, all HandlerManager  are available from the InstanceManager (the HandlerManager associated to the subscriber handler is not null). I have attached a picture to illustrate this.
