You are right - all classes from the rt.jar should be loaded using the 
system class loader. What's confusing me is that you say "it has 
references to classes" - of course, the another class loader can have 
references to those classes, but it should not define them.

Check out the "Java Basics" -> "Class Loader Explorer". It shows all class 
loaders, the classes the define and their parent class loader. I just ran 
this query on two dumps and could not find any problems. Do not hesitate 
to copy and paste the view to this forum to discuss.
