All Implemented Interfaces:
Serializable
public class EmptyAuthorException extends Exception
Checked exception thrown when an attempt is made to create or process a review without a valid author (customer).

This typically occurs in the Review entity or in methods such as Customer.makeReview(com.goldenleaf.shop.model.Product, java.lang.String, int). The author field must reference a persisted Customer and must not be null.

Example scenarios that trigger this exception:

  • Passing null as the customer when creating a review
  • Trying to save a review with an unassigned or detached author
  • Business logic violation where anonymous reviews are not allowed

This is a checked exception, forcing the caller to handle or declare it — appropriate for validation errors that are recoverable and expected in normal application flow.
