以编程方式创建EntityManagerFactory会在wildfly中产生NullPointerException

Question

当以编程方式创建EntityManagerFactory时，当persistence.xml包含节点<mappig-file>时，它会生成Nullpointer。

我在Wildfly wildfly-10.1.0.Final 上进行了测试 我试图通过添加这些jar文件然后编辑module.xml指向新的jar来将Hibernate hibernate-core-5.0.10.Final更新为hibernate-core-5.2.10.Final：

以编程方式创建EntityManagerFactory的代码示例：

persistence.xml的XML示例：

它会在第37行产生一个nullpointer？¿？ ：S（构造函数的最后一个括号。）

有没有人知道为什么会发生这种情况？ 当我删除它的工作原理。即使我删除了orm.xml的内容，它也会给出NullPointerException。 您可以看到我已将其调试到该行，并且那里应该发生NullPointerException，因为它是构造函数的结束括号。

我想将orm.xml添加到persistence.xml的原因是因为我想添加一个不属于domain.jar的EntityListener（实体生命所在的位置）。
EntityListener包含一些业务逻辑 因此，如果有人知道实现此目的的解决方法，那也是受欢迎的，但当然我更喜欢修复NullPointerException。

编辑：显然，这些断点通常是不同版本的结果。但是，我们检查了以下地方：pom.xml; .m2 Maven文件夹; Wildfly部署文件夹; Eclipse库和Maven库;调试时getClass().getProtectionDomain().getCodeSource().getLocation‌​()。所有这些都给出了完全相同的结果：版本5.2.10.Final.jar。

如果有人知道任何其他地方寻找可能导致此问题的潜在不同版本，我很想知道。
