If no transaction is in progress when the event is fired, they are * notified at the same time as other observers. * If the transaction is in progress, but {@link jakarta.transaction.Synchronization} callback cannot be registered due to the transaction being already * marked for rollback or in state where {@link jakarta.transaction.Synchronization} callbacks cannot be registered, the {@link #BEFORE_COMPLETION}, * {@link #AFTER_COMPLETION} and {@link #AFTER_FAILURE} observer methods are notified at the same time as other observers, * but {@link #AFTER_SUCCESS} observer methods get skipped. *
