----------------------------------------

             Summary: JDBC client crashes after successful authentication if trace logging is enabled.
                 Key: DRILL-5589
                 URL: https://issues.apache.org/jira/browse/DRILL-5589
             Project: Apache Drill
          Issue Type: Bug
    Affects Versions: 1.11.0
            Reporter: Sorabh Hamirwasia
            Assignee: Sorabh Hamirwasia


When authentication is completed then with latest changes we [dispose the saslClient instance | https://github.com/apache/drill/blob/master/exec/java-exec/src/main/java/org/apache/drill/exec/rpc/security/AuthenticationOutcomeListener.java#L295] if encryption is not enabled. Then later in caller we try to [log the mechanism name | https://github.com/apache/drill/blob/master/exec/java-exec/src/main/java/org/apache/drill/exec/rpc/security/AuthenticationOutcomeListener.java#L136] using saslClient instance with trace level logging. This will cause the client to crash since the saslClient instance is already disposed before logging.
