Review Comment:
Why `RuntimeException`? Can't we catch `ConfigException` and
`StreamsException` in one catch clause and then throw a `StreamsException`.
This seems safer to me, because otherwise with future code changes that might
throw exceptions like `IllegalStateException` we would wrap unexpected
exception due to mistakes in Streams in `StreamsException`.
```java
catch (final ConfigException | final StreamsException ex) {
// handle the exception
}
```
