매핑 된 @Peristent InputStream 필드가있는 레코드를 유지하려고합니다. 컨텍스트 : JDK 1.8, LiferayPortal on Tomee 1.7.1 (OpenJPA 2.4 패치). Liferay에 의해 오염 된 stacktrace에 대해 죄송합니다.OpenJPA에 영구 입력 스트림이있는 레코드를 유지할 수 없습니다.
@Entity

그리고 지속 :
logo = new FileEntry();
logo.setContent(new FileInputStream("some_local_file"));
entityService.persist(logo);
