Y'all:

In order to fix defect #3870, I need a check to see if a class is "built-in". In the implementation of Ruby, there is a concept of a "built-in" class. This is held in flags that are carried around with the class information. As far as I can tell, this applies to Object, Class, Module, etc. It keeps Ruby from returning singleton methods for these classes, as an example.

Is there a similar concept in JRuby, or does it need to be built? Or is there another (better) way?

What flag exactly is it you're trying to mimic?
