Hello,

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

If this solution doesn't help, please have a look at this topic:

https://community.talend.com/s/question/0D53p00008021ziCAA/an-illegal-reflective-access-operation-has-occurred

And let us know if there is any incompatible jar file in your subjob.

Best regards

Sabrina

Hello,

What happens when you type .....

java -version

...in your terminal window?

Please try to to specified -vm to point to java executable path in Talend-Studio-macosx-cocoa.ini like:

-vm

/Library/Java/JavaVirtualMachines/zulu-8.jdk/Contents/Home/bin/java

Add Java path to Info.plist inside Talend-Studio-macosx-cocoa/Contents like:

<string>-vm</string><string>/Library/Java/JavaVirtualMachines/zulu-8.jdk/Contents/Home/bin/java</string>

Feel free to let us know if it helps.

Best regards
