Illegal class operation (Reviewer Review)
Class operations (static operations) cannot be abstract (there's no object to use polymorphically) or immutable (there's no object to change).
Consequences
An operation with this set of options makes no sense.
Strategy
Make the operation an instance operation or remove the modifiers.
