Wrong

Right

Detection

New exceptions should override behavior methods.

No. code, description, resumable, etc are not behavioral.

Conclusion

You would not create different classes for every Person instance, so they return different names. Why would you do it with exceptions.

How often do you catch a specific exception?.

Go out and check your code.

Is it necessary to be a class?

You are already coupled to the class. Couple to the description instead.

Exception instances should NOT be Singletons.

Relations

You will fall to ruin because you believe that exceptions to the rule make new rules.
