There is no problem when I do the same with jython-standalone-2.7.1.patch2618.jar

I'm using the 11.0.5 version of Java.

Could you help ?
Thank you in advance.

Regards
Alexandre

We encountered same problem with Robot Framework (robotframework/robotframework#3780). It seems that module-info.class file in the root of jython-standalone.2.7.2.jar is causting the problem. Older jar versions don't contain that file and I assume it's there by an accident.

Got it working by using fastjar instead of jar.
