类型检查失败，出现内部断言错误

Question

当我尝试对实现未类型化协议的记录进行类型检查时，我得到了内部断言错误。最小示例

(defprotocol Lifecycle
  (start [component]))
  (stop [component]))

(t/ann-record TestRec [host :- String
                       port :- Integer
                       connection :- String])
(defrecord TestRec [host port connection]
  Lifecycle
  (start [component]
    (let [connection (str "Host: " host ", port: " port)]
      (assoc component :connection connection)))
  (stop [component]
    (.close connection)))
