Print more information about class loaders in IllegalAccessErrors
 
Since Java 9, class loaders have a name field. Report this if set.
Also report the parent class loader.
It was decided to not report the parent class loader, but to add the module.
The exceptions now use a unified reporting utility for the module/loader information.
