Review Comment:
Good catch here. Should we do the same in the
[NumberConverter](https://github.com/apache/kafka/blob/30216ea1c58761e62f51af40033f24e3ae1c5c2a/connect/runtime/src/main/java/org/apache/kafka/connect/converters/NumberConverter.java#L123-L125)
class?

Review Comment:
Also, even though these are no-ops right now, if we want to be meticulous
about the cleanup logic here, should we wrap both of these in
`Utils::closeQuietly`, so that if one fails, we still get a chance to close the
other?
