```Python
old_dict = {
    "old key": "old value",
    "second old key": "second old value",
}
new_dict = {**old_dict, "new key": "new value"}
```

Here, `new_dict` will contain all the key-value pairs from `old_dict` plus the new key-value pair:

```Python
{
    "old key": "old value",
    "second old key": "second old value",
    "new key": "new value",
}
```

                logger.debug("{}.{}.Handler does not exist.", basePackage, protocol, e);
            } catch (final NoSuchFieldRuntimeException e) {
                logger.debug("{}.{}.Handler does not contain PROTOCOL_TYPE.", basePackage, protocol, e);
            } catch (final Exception e) {
                logger.warn("Cannot load Handler from {}.{}", basePackage, protocol, e);
            }
        });
    }

3.x, null would yield a username or password of "null".

#### HttpUrl.queryParameterValues()

The return type of `HttpUrl.queryParameterValues()` is `List<String?>`. Lists that may contain null
are uncommon and Kotlin callers may have incorrectly assigned the result to `List<String>`.
