----------------------------------------
Issue priority based on previous instance in KAFKA-7168
> Broker shutdown during SSL handshake may be handled as handshake failure
> (Regression)
> -------------------------------------------------------------------------------------
>
> Key: KAFKA-9021
> URL: https://issues.apache.org/jira/browse/KAFKA-9021
> Project: Kafka
> Issue Type: Bug
> Components: security
> Affects Versions: 2.0.1, 2.1.1, 2.2.1, 2.3.1
> Reporter: Graham Campbell
> Priority: Major
>
> [Java 11 throws an
> SSLProtocolException|http://hg.openjdk.java.net/jdk/jdk11/file/1ddf9a99e4ad/src/java.base/share/classes/sun/security/ssl/Alert.java#l125]
> when a SSL connection is gracefully closed during handshaking instead of an
> SSLException. This breaks the fix for KAFKA-7168 and the client may process
> the resulting SSLException as a non-retriable handshake failure rather than a
> retriable I/O exception.
