That is a strange request, since if ClassB inherits ClassA => ClassB is
a specialization of ClassA.
Anyway, did you tried something like bellow?
ClassA( class != ClassB.class )
This does not look like a "business" rule, though... but I don't know
your use case...

I have two classes, ClassA and ClassB. ClassB inherits from ClassA. I
have a need to write a rule that only matches instances of ClassA without
matching instances of ClassB. How I can I do that?
Thanks
