[jira] [Commented] (KAFKA-14012) passing a "method" into the `Utils.closeQuietly` method cause a no-op call

["Chris Egerton (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KAFKA-14012?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17556384#comment-17556384 ] 

Chris Egerton commented on KAFKA-14012:
---------------------------------------

[~showuon] when does this no-op occur? The bugs that I've found related to {{Utils::closeQuietly}} have been NPEs caused by method references of null objects; I believe as long as the object is non-null and the correct method is referenced, things should go smoothly.

> Utils.closeQuietly method accepts `AutoCloseable` object, and close it. But there are some places we passed "method" into Utils.closeQuietly, which causes the object doesn't get closed as expected. 
> I found it appeared in:
> - WorkerConnector
> - AbstractWorkerSourceTask
> - KafkaConfigBackingStore
