eclipselink error on multithreaded environment

Question

각 스레드가 자체 엔티티 관리자를 사용하도록 보장하기 위해 ThreadLocal을 사용하는 다중 스레드 환경에서 최신 eclipselink (2.5.2)를 사용하고 있으며 아래 예외가 발생합니다.

인터넷을 통해 인터넷 검색 나는 유사한 환경에서 버전 2.3에서 일어난 것을 깨달았다. 누구든지 그 방법을 알고 있습니까? 어떻게 이것을 극복 할 수 있습니까?

EclipseLink Bugzilla에는 Writer에서이 코드 조각에서 NPE와 관련된 알려진 문제가없는 것처럼 보입니다. https://bugs.eclipse.org/bugs/enter_bug.cgi?product=EclipseLink 에 새 버그를 만드십시오.이 정보와 간단한 재생 시나리오 (가능하면 테스트 케이스)를 입력하십시오. 우리는 그것을 살펴볼 것입니다.
