      I think this issue is rasied because the base image is still on JAVA 11. ref :  https://github.com/debezium/container-images/blob/main/base/latest/Dockerfile#L7

       

      Do you see the same behaviour using the latest relesead Debezium version?

      (Ideally, also verify with latest Alpha/Beta/CR version)

      Yes

      Do you have the connector logs, ideally from start till finish?

      (You might be asked later to provide DEBUG/TRACE level log)

      <Your answer>

      How to reproduce the issue using our tutorial deployment?

      Start the Debezium docker Image.

       

      Implementation ideas (optional)
