EntityManager не внедряется и имеет значение null при обновлении с jdk 8 до jdk 21 на сервере Liberty. ⇐ JAVA

[Anonymous]

У меня было приложение, которое отлично работало на jdk 8 и Liberty 22.0.0.10. Я обновляю свое приложение до jdk 21 на Liberty 24.0.0.9 и изменяю pom.xml и некоторые функции на сервере. Приложение запускается, конечные точки REST и очередь jms работают, но при вызове базы данных она получает нулевой указатель, поскольку менеджер объектов em не внедряется (в jdk8 он внедряется правильно и не равен нулю). Выдает эту ошибку:
nliberty.opentracing.internal.OpentracingJaxRsEMCallbackImpl W CWMOT0009W: The OpenTracing exception mapper detected and is handling an unhandled exception from the JAX-RS application.
java.lang.NullPointerException: Cannot invoke "javax.persistence.EntityManager.find(java.lang.Class, Object)" because "this.em" is null

Я использую библиотеку jpa-2.2, и отсюда кажется, что jdk 21 поддерживается. Это наиболее важная часть моего pom (я обновил некоторую библиотеку из версии jdk8):

Я пытался использовать jakarta вместо javax, но безуспешно (это также сломало мою очередь jms), есть идеи, как исправить этот нулевой указатель?
Изменить:
@Джаред: у меня уже был javax.annotation:javax.annotation-api:1.3, просто исключил его из pom, чтобы он не выглядел слишком длинным.
