The Java Commons Annotations Was Removed in JDK 11

The Java Common Annotations Module was deprecated in Java version 9 and was removed in java version 11. So what does this mean for your AEM 6.5 project running on JDK 11?

AEM 6.5 and JDK 11

As of AEM 6.5, JDK 11 is supported along side JDK 8. As such, Devs will begin developing and testing AEM on JDK 11 you can check the technical requirements and see Adobe’s notes on JDK 11. You should also read the Oracle/Adobe License Agreement. also read Dan’s post on the matter here.

and you’ll see it uses this dependency:


You can use whichever dependency works for you, so long as you have it in your project!
