jpa - Weblogic 12c中的beforeCompletion中的JPA意外异常

Question

在执行纯 JPA 托管事务期间，我使用命名查询从数据库中获取实体 A，在对其状态进行几次更新后，我再次合并 A 实体。合并的结果是实体的正确合并实例，但是当方法提交时，我有以下异常：

weblogic.transaction.RollbackException: Unexpected exception in beforeCompletion: sync=org.eclipse.persistence.transaction.JTASynchronizationListener@76d1f39e
PersistenceUtil.getIdentifier(entity) was called with object [...EntityA@6d5f707] which is not a persistent object.

托管实体如何不是持久对象？persistence.xml 文件中有实体，对该实体的命名查询正确执行，合并也成功执行。

我使用 Weblogic 服务器 12.2.1.3.0。JPA 引擎的 Eclipselink 和 Java 8 的 JEE7。奇怪的是，如果我在不提供新 EAR 的情况下更新 WebLogic 中的部署，问题就解决了。

任何提示都是有益的。
