module-info.java should contain "requires java.logging"

Version 4.6.32

When I run new ClassGraph().verbose().scan() under IntellJ IDEA I get:

Exception in thread "main" java.lang.IllegalAccessError: class nonapi.io.github.classgraph.utils.LogNode (in module io.github.classgraph) cannot access class java.util.logging.Logger (in module java.logging) because module io.github.classgraph does not read module java.logging
	at io.github.classgraph@4.6.32/nonapi.io.github.classgraph.utils.LogNode.<clinit>(LogNode.java:51)
	at io.github.classgraph@4.6.32/io.github.classgraph.ClassGraph.verbose(ClassGraph.java:103)

I believe adding requires java.logging to your module-info.java file will fix this problem.

I just verified the fix in master fixes the error in my application. Thank you!

I would say make it requires static java.logging - it is only needed when verbose is on

This is reasonable, but given that it is a java.util class, won’t it always be present in any JRE?

And actually, requires static is not ideal. From: https://blog.codefx.org/java/module-system-optional-dependencies/

As a consequence even if a module is present on the module path (or in the JDK for that matter), it will not be added to the module graph just because of an optional dependency. It will only make it into the graph if it is also a regular dependency of some other module that is being resolved or because it was added explicitly with the command line flag --add-modules.
