I use Springboot 2.5.8 and azure-spring-data-cosmos:3.14.0. This was perfectly working with JDK11. But, when I tried upgrading JDK 1to 17, it started giving the below errors:

How to resolve this issue. As per the the spring-data-cosmos documentation, it is expected to work JDK8+

I checked if upgrading azure-spring-data-cosmos is an option for us. But, we don’t want to upgrade spring boot at the moment.
