-----------------------------------------
Summary: TLSv1.3 and Java 11
Key: IGNITE-15336
URL: https://issues.apache.org/jira/browse/IGNITE-15336
Project: Ignite
Issue Type: Improvement
Affects Versions: 2.10
Reporter: Alexey Kukushkin
Enhance Ignite to support TLSv1.3 with Java 11.
Ignite currently does not support TLSv1.3 with Java 11. This is
[documented|https://ignite.apache.org/docs/latest/setup#running-ignite-with-java-11-or-later]:
_TLSv1.3, which is available in Java 11, is not supported at the moment.
Consider adding {{‑Djdk.tls.client.protocols=TLSv1.2}} if SSL between nodes is
used._
h3. Reproducer
The problem can be reproduced by trying to connect an Ignite Java thin client
to Ignite server over an secure connection.
Add TLSv1.3 to the list of protocols in {{SSLContext}} and set the
{{SSLContext}} in the {{ClientConnectorConfiguration}} on the server and
{{ClientConfiguration}} on the client.
An attempt to {{Ignition.startClient({sslContext: {protocols: ['TLSv1.3']}})}}
fails with a {{ClientConnectionException}} saying _Channel is closed_.
