 ## Frequently Asked Questions
 
+**Q: I'm seeing a warning about Java 8. What should I do?**
+
+**A:** Version 9.x is the last major version to support Java 8. Support ends on June 30, 2026. Future versions (10.0+) will require Java 11 or later. If you are running Java 8, you have two options:
+1. **Recommended**: Upgrade your Java runtime to Java 11 or later
+2. Pin your SDK version to 9.x in your dependency configuration (though you will miss out on future updates and bug fixes)
+
+The warning appears once per application lifecycle and does not affect functionality.
+
 **Q: What happened to [`com.vonage:client`](https://search.maven.org/artifact/com.vonage/client)?**
 
 **A:** To avoid confusion with our various client-side SDKs, this server-side SDK has been moved from
