Summary

The API for method: j.l.c.ClassDesc::nested(String, String...) states that it will throw an exception if any argument is null and the implementation must enforce this assertion

Problem

The API for method: j.l.c.ClassDesc::nested(String, String...) states that it will throw an exception if any argument is null. The implementation is not enforcing this assertion
