> ServiceRegistryImpl uses a HashMap which is not thread-safe.
> Services can be initialized lazily which means several threads can end up asking for the same service in //

> note that using a ConcurrentHashMap is not good enough as we probably don't want the same service type to be initialized multiple times.
