我已将我的 Eclipse IDE 从 Helios 升级到 Juno。我已经更新了我的项目以使用 Juno 附带的最新版本的 EclipseLink，它是 2.4 Nightly（如持久性属性中所示）。我有一个项目本身就是一个 JPA 项目 (ProjectA)，它依赖于另一个 JPA 项目 (ProjectB)。所以实际上，我有一个项目正在与 2 个单独的数据库通信。当我尝试启动在 Tomcat 下运行的 ProjectA 时，出现下面列出的异常。异常中提到的实体都位于依赖项目 - ProjectB 中。我已经重建了两个项目并重新部署。
我想知道 2.4 是否不是从 2.1.3 直接升级，并且我错过了一些升级文档，其中详细说明了我需要对我的 JPA 项目的配置进行的更改。
将 ProjectA 和 ProjectB 都恢复为 EclipseLink 2.1.3，一切正常
为了节省空间，我只列出了其中一个实体的部分例外情况，但对于项目 B 中定义的每个实体，它都会重复。

需要明确的是 - 如果我自己部署 ProjectB，那么它会按预期工作。仅当我部署依赖于 ProjectB 的 JPA 项目 A 时才会出现问题。ProjectA 正确打开它自己的持久性上下文，但不是 ProjectB。
我已按要求附上了persistance.xml。
