Hello,

Are you using Oralce JDK or Open JDK?

We met this issue before and it appears like this is a known warning with Open Zulu JDK11 regarding the Reflection packages in Java. Reflection, among other things, lets you access every detail of an object even if the developer doesn’t want you to. This warning is telling you that this is a feature that might be restricted (or not available) in the future. This typically will not prevent the Job from running or completing.

Please try to use OpenJDK 8/ Oracle JDK and the warning message will go away. Make sure JAVA_HOME is also set to this version of Java.

Let us know if it helps and we will appreciate it a lot if you could give us more information about your situation.

Best regards

Sabrina
