findReferencePathToObject: not intended for use with Classes/Metaclasses
The method Repository >> findReferencePathToObject: can be used to find
references to objects in the repository, to determine why these instance
are not garbage collected. Due to the design of the code, this method
does not work to find references to instances of Class or MetaClass.

If this is not enough information, you can use findReferencePathToObject:
to find a reference path each of the objects returned by listReferences:.
