Guillaume Nodet commented on ARIES-802:
---------------------------------------

I think the reset method should be called each time before the fist call to registerComponentDefinition.
Somethig like 
{code}

                        if (missing.size() > 0) {
                            LOGGER.info("Bundle {} is waiting for namespace handlers {}", bundleContext.getBundle().getSymbolicName(), missing);
                            eventDispatcher.blueprintEvent(new BlueprintEvent(BlueprintEvent.GRACE_PERIOD, getBundleContext().getBundle(), getExtenderBundle(), missing.toArray(new String[missing.size()])));
                            return;
                        }
                        componentDefinitionRegistry.reset();
                        componentDefinitionRegistry.registerComponentDefinition(new PassThroughMetadataImpl("blueprintContainer", this));
{code}

> I saw this problem several months ago. This problem still occurs in the current trunk 0.4.1-snapshot. 
> I have two bundles A and B running and A depends on B. In my concrete case, A is an application scenario bundle depending on B the cxf bundle.
> Initially, both are running and have status Active. When I stop B, A goes to status GracePeriod. When I start B again, A is started but does not come back to status Active but goes to status "Failure" with the following error:

> The cause of this problem seems to be that this bundle's blueprint container's component definition map is not cleared up prior to getting restarted. This calls ComponentRegistryImpl's registerComponentDefinition and this method checks if the same named component is already in the map. 
> I added a line of code to clear up the definition map and this made the bundle start and its status go to Active.
> Please take a look at the attached file.
