[logback-dev] I don't understand ClassPackagingDataCalculator :p

Hi Ceki. I was just checking out ClassPackagingDataCalculator because I wanted to see what the warning [WARNING] [,,]\logback-classic\src\main\java\ch\qos\logback\classic\spi\ClassPackagingDataCalculator.java:[17,18] sun.reflect.Reflection is Sun proprietary API and may be removed in a future release was about and I have to admit that I don't get it. What are you doing with the caller class? What would be the problem of just Class.forName for the STE class names? This isn't meant as critique, I would just like to understand what the code does, and why ;) Regards, Joern.
