java.lang.ArrayStoreException IBM Websphere

Question

每当我尝试使用JPA 2.0和Websphere运行更新查询时，都会收到java.lang.ArrayStoreException。我正在使用测试实用程序，并且我成功更新了正确的行等等，没有事务回滚，我只是得到该异常并且我的应用程序不执行。我怎样才能解决这个...我不知道，如果堆栈跟踪，你会做你任何好处......但由于这保险业监督堆栈溢出，我想我会anywho它张贴...

每我查找异常我得到的建议，一些类型不匹配？但我不知道是这样。一切似乎都很好......我错过了什么？有人有任何洞察，为什么会发生这种异常？

Answer 1

没有看到任何代码，我不得不说你在混合你的类型。 http://docs.oracle.com/javase/1.4.2/docs/api/java/lang/ArrayStoreException.html

您是否使用任何继承，对象或多态并且不严格遵循这些类型？

我就从这里开始：
