Update Talend 7.1.1 => 7.2.1: Update Java 11

[Anonymous]

Hi

i'm currently working on updating Talend and Java.

So far i could succesfully update vom Talend OS ESB 7.1 to Talend OS DI 7.2.1 (we dont need the ESB-Part anymore). With existing Java 8 everything runs fine. Now i'm trying to Update from Java 1.8 to Java 11.

On my local computer Java 11 is installed:

Also JAVA-HOME and JRE_HOME point to JDK 11:

Its also included in PATH: (First and only entry pointing to Java there):

If i start old Talend 7.1 it is not working anymore.

If i start Talend 7.2. it starts normal and project is imported.

So it seems fine to me.

But my problem is that i can't set the Java compiler compliance to 1.11 in Studio. In Project settings my only option is 1.8:

In preferences i have following Settings:

In Preferences->Java->Compiler i can change "Compiler compliance level":

If i choose 1.8 there it even warns me about:

But the setting there is not saved. It doesnt seem to have any effect and when i restart Talend its again reset to 1.8. I can not set and keep Java 11.

If i build after set to 11 there it still runs with Java 8.

Can anyone help me here? I don't know what else i can do anymore.

Thank you und kind regards,

Sven
