When multiple users attempt to pay fines simultaneously for the same account, or when system processes (like fine accrual cron jobs) run concurrently with user payments, we need to ensure data consistency.
Acceptance Criteria:
Implement optimistic locking using versioning or timestamps on the Fine entity
Add retry logic for concurrent update scenarios
Ensure fine amount calculations are atomic
Add appropriate error handling and user feedback for concurrent modification conflicts
Technical Notes:
Consider using @Version annotation with JPA or implement a custom optimistic locking mechanism.
