centers. OkHttp supports modern TLS features (TLS 1.3, ALPN, certificate pinning). It can be
configured to fall back for broad connectivity.

Using OkHttp is easy. Its request/response API is designed with fluent builders and immutability. It
supports both synchronous blocking calls and async calls with callbacks.

A well behaved user agent
-------------------------

OkHttp follows modern HTTP specifications such as

        Secured secured = SecuredInterfaceImpl.class.getAnnotation(Secured.class);
        assertNull(secured); // Interface annotations are not inherited by implementing classes
    }

    // Test annotation array immutability
    @Test
    public void test_annotationValueImmutability() {
        Secured secured = MultipleRolesClass.class.getAnnotation(Secured.class);
        String[] roles1 = secured.value();

    }
  }
}
```
