Astra Driver 3.8.0 Operation Timed out

I have a sample application on java 11,14,15 which is not able to connect to Astra with the 3.8.0 driver.

Caused by: com.datastax.driver.core.exceptions.NoHostAvailableException: All host(s) tried for query failed (tried: 646adb8d-4395-43ac-a50d-048518df238b-us-east1.db.astra.datastax.com/<unresolved>:32403:7491c008-93fb-49b9-a184-48067543c043 (com.datastax.driver.core.exceptions.OperationTimedOutException: [646adb8d-4395-43ac-a50d-048518df238b-us-east1.db.astra.datastax.com/<unresolved>:32403:7491c008-93fb-49b9-a184-48067543c043] Operation timed out))

I have created a 4.9.0 example (to show working app framework):

https://github.com/ds-steven-matison/astra-connection

And here is the 3.8.0 example (minimal changes from app source):

https://github.com/ds-steven-matison/astra-connection-3.8

fwiw: the app source works with 3.8.0 driver on openjdk1.8, not 11+

Testing command is:

mvn clean compile exec:java -Dexec.mainClass=App.java

Some things I have tried:

- TLS argument in mvn command

- increasing timeout with socketOptions

- feeding TLS to maven env variable

- trying to execute as jar w/ tls args


Can anyone provide a work around?

The solution command for java 8 with 3.8.0 driver is:

% mvn clean compile exec:java -Dexec.mainClass=App.java -Djdk.tls.client.protocols="TLSv

and the expected output is:
