How to prevent java.lang.IllegalAccessError with JDK11?

We receive the follow exception in our test system. Any idea how we can prevent this exception for example with a command line switch. And any idea how this exception can occur?

Can the completely access check be disabled in a test system that use intensively reflection and class loading?

java.lang.IllegalAccessError: class java.io.File (in module java.base) cannot access class javax.print.PrintException (in module java.desktop) because module java.base does not read module java.desktop

We solve the problem by updating JMockit version 1.31 with the current version 1.44. It look like the old version is not compatible with the current version.

Try to run it by adding the following command argument.

--add-reads java.base=java.desktop
