Reproduction: - create ProxyLookup with one lookup that contains one object i.e. String - perform lookup via Template of String.class - replace lookup in ProxyLookup. New lookup will contain one object i.e Integer - perform lookup via Tempate of String.class -> instance of String.class is found, although it already shouldn't be presented in ProxyLookup For more details, see attached test diff
