> I've been looking at VisualVM heap dumps after restarting some custom bundles in Karaf and noticed the stopped services (exported via DOSGi) linger in memory and are never garbage collected (screenshot attached, StoreServiceImpl being the lingering custom service). Browsing through the instance hierarchy from the snapshot I found something suspicious - org.apache.cxf.endpoint.ServiceImpl registers the ManagedEndpoint with the ServerLifeCycleManager, but doesn't seem to unregister it when the instance is destroyed. Could this be the memory leak preventing the old bundles from being collected?
