    Description

      When logback is running with Java Modules (JPMS) an attempt to use JULHelper by any code fails with the following error:

      Exception in thread "main" java.lang.IllegalAccessError: class ch.qos.logback.classic.jul.JULHelper (in module ch.qos.logback.classic) cannot access class java.util.logging.Level (in module java.logging) because module ch.qos.logback.classic does not read module java.logging
 at ch.qos.logback.classic@1.4.1/ch.qos.logback.classic.jul.JULHelper.asJULLevel(JULHelper.java:45)
 at com.github.agavrilov.logback@1.0-SNAPSHOT/com.github.agavrilov.logback.Main.main(Main.java:9)

      I noticed this while using LevelChangePropagator in my program.

      Most probably the logback.classic module is missing "requires java.logging" declaration in its module-info.java.

      You can execute the run.sh script from the repository below to reproduce the problem:
