Jpa 未引用的persistenceunit init引发DuplicateServiceException:\uuuu FIRST\u PHASE\uuuuu已注册？

我在Wildfly 8.1中部署了多个war和ear。最近，我将一些代码从hibernate迁移到了jar中的jpa中，jar由ear和war共享

yy.ear
 -> persistence.xml(ds2,ds3,ds4)
 -> myjpa.jar
    ->persistence.xml(ds1)
xx.war
 -> myjpa.jar
    ->persistence.xml(ds1)

现在，yy.ear还有persistence.xml（引用ds2、ds3和ds4），myjpa.jar也有persistence.xml（仅引用ds1）。但是在部署过程中看到的错误是xx.war正在尝试重新初始化ds4。我已经检查了所有的源代码，但在xx.war或myjpa.jar中没有看到对ds4的引用。那么如何修复这个部署错误呢？服务器日志如下

另外，为了添加yy.ear，可以正确部署，但xx.war不能

问题是具有过时模式的表。一旦删除这些命令，部署将在没有任何错误的情况下完成
