Innodb блокиране, не е споменато в ENGINE INNODB STATUS

Получавам изключение за блокиране, но когато искам да видя малко информация за това от „ПОКАЖЕТЕ СЪСТОЯНИЕТО НА INNODB НА ДВИГАТЕЛЯ“, то съдържа информация за блокиране от по-отдавна (много преди изключението), така че изглежда, че просто „не е уловено“ по тази команда.

От stacktrace мога да видя, че последният изпълнен код на моето приложение беше $Proxy174.attemptToAcquireJobExecution, което е реализация на пролетния интерфейс за данни:

@Transactional(TxType.REQUIRES_NEW)
@Modifying
@Query("UPDATE Job SET last_run = NOW(),
                       last_run_by=:runner
         WHERE name = :name
           AND (last_run + :interval ) < NOW()")
int attemptToAcquireJobExecution(
           @Param("name") String var1,
           @Param("interval") int var2,
           @Param("runner") String var3);

Работи върху такава проста маса:

CREATE TABLE `jobs` (
  `name` varchar(50) COLLATE utf8mb4_unicode_ci NOT NULL,
  `last_run_by` varchar(100) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
  `last_run` datetime(3) DEFAULT NULL,
  `context_data` varchar(100) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
  PRIMARY KEY (`name`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

Планираните задачи, които изпълняват тази команда, се изпълняват на всеки няколко минути (на 3 екземпляра на приложение), така че има наистина минимален риск от сблъсъци, но блокиране възниква много често... Няма @Transactional никъде преди тази операция, така че трябва да има наистина няма висяща транзакция. Както и да е, ping на тези команди дава празни резултати:

SELECT * FROM INFORMATION_SCHEMA.INNODB_LOCKS ;
SELECT * FROM INFORMATION_SCHEMA.INNODB_LOCK_WAITS;

Оригинален stacktrace, моите класове са маркирани като "xxx", в долната част:
