-------------------------------------
Summary: Connect header converters never closed
Key: KAFKA-14007
URL: https://issues.apache.org/jira/browse/KAFKA-14007
Project: Kafka
Issue Type: Bug
Components: KafkaConnect
Reporter: Chris Egerton
The [HeaderConverter
interface|https://github.com/apache/kafka/blob/1e21201ea24389bdaccb8a462f3a53e356b58a58/connect/api/src/main/java/org/apache/kafka/connect/storage/HeaderConverter.java#L27]
extends {{Closeable}}, but {{HeaderConverter::close}} is never actually
invoked anywhere. We can and should start invoking it, probably wrapped in
[Utils::closeQuietly|https://github.com/apache/kafka/blob/1e21201ea24389bdaccb8a462f3a53e356b58a58/clients/src/main/java/org/apache/kafka/common/utils/Utils.java#L999-L1010]
so that any invalid logic in that method for custom header converters that has
to date gone undetected will not cause new task failures.
