 *  Fix: Lock in a route when recovering from an HTTP/2 connection error. We had a bug where two

   * that have nullable bounds? Unfortunately, if we change the parameter to TypeParameter<? extends
   * @Nullable X>, then users might pass a TypeParameter<Y>, where Y is a subtype of X, while still
   * passing a TypeToken<X>. This would be invalid. Maybe we could accept a TypeParameter<@PolyNull
   * X> if we support such a thing? It would be weird or misleading for users to be able to pass
