> I mean use a derived class of `Exception` as the checked exception. You
replaced `Exception` with `RuntimeException`, which is worse because
`RuntimeException` is an unchecked exception. Take
`org.apache.pulsar.metadata.api.MetadataSerde` as an example:
>
> ```java
> public interface MetadataSerde<T> {
>
> byte[] serialize(T value) throws IOException;
>
> T deserialize(byte[] content) throws IOException;
> }
> ```
>
> It checks `IOException` that derives from `Exception`. You can also some
many other interfaces in Pulsar that checks `PulsarAdminException` or
`PulsarClientException`, not `Exception` directly.
>
> Though IMO it's a better practice, using `Exception` directly is also okay
but don't use `RuntimeException` as the checked exception.
