Hi, as noted in SLING-3400 we have a problem when a resource provider factory is unregistered and a resource resolver is currently using a provider from this factory. In that case, that reference is never cleared. This problem occurs due to long running resource resolvers.
I looked at solving this issue and my first idea was to simply remove the reference to the provider if the factory is unregistered. Unfortunately, this comes with the drawback that we have to keep a reference to all open resource resolver (contexts) in order to notify them, once a factory is removed. Although this is feasible, while implementing it I came to the conclusion that this is actually the wrong approach: a resource resolver is using / has used a provider and this one silently disappears. This might cause some trouble / unexpected behaviour. So I rather think, once this happens all resource resolvers need to be closed and recreated - the easiest way to do this is to unregister and reregister the resource resolver factory. However, I think simply modifying the service registration of the resolver factory would be the better option and should do the trick. WDYT? Regards Carsten -- Carsten Ziegeler cziege...@apache.org
