从EclipseLink 2.1.3升级到EclipseLink 2.4 Nightly之后，应用程序将无法启动

Question

我已将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EclipseLink的最新版本，每晚2.4（显示在Persistance属性中）。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，我有一个与2个单独数据库交谈的项目。当我尝试启动在Tomcat下运行的ProjectA时，我得到下面列出的异常。例外中引用的实体都位于依赖项目 - ProjectB中。我重建了两个项目并重新部署。

我想知道2.4是不是2.1.3的直接升级而且我错过了一些升级文档，详细说明了我需要对我的JPA项目配置所做的更改。

将ProjectA和ProjectB恢复为EclipseLink 2.1.3，一切正常

我已经列出了仅有一个实体可以节省空间的部分例外情况，但是对于项目B中定义的每个实体都会重复。

要清楚 - 如果我自己部署ProjectB，那么它会按预期工作。只有当我部署JPA项目A时才会出现问题，该项目对ProjectB具有依赖性，从而发生问题。 ProjectA正确地打开了它自己的持久化上下文，但不是ProjectB的。

我已按要求附加了persistance.xml。

项目A;

似乎是一个编织问题。看起来对象没有发生编织。确保正确启用编织。如果您使用静态编织，请确保使用2.4静态编织您的类。

尝试禁用编织以确认问题。还包括你的persistence.xml。
