[jira] [Created] (KAFKA-7712) Handle exceptions from immediately connected channels in Selector

Rajini Sivaram created KAFKA-7712:
-------------------------------------

             Summary: Handle exceptions from immediately connected channels in Selector
                 Key: KAFKA-7712
                 URL: https://issues.apache.org/jira/browse/KAFKA-7712
             Project: Kafka
          Issue Type: Bug
          Components: network
            Reporter: Rajini Sivaram
            Assignee: Rajini Sivaram
             Fix For: 2.2.0


We try to handle all possible exceptions in Selector to ensure that channels are always closed and their states kept consistent. For immediately connected channels, we should ensure that any exception during connection results in the channel being closed properly and removed from all maps. This is a very unlikely scenario, but we do already handle the exception. We should clean up properly in the catch block.
