我正在开发一个用于个人财务监控的Web应用程序。从EclipseLink切换到Hibernate后，我遇到了以下异常。当应用程序尝试通过CashFlowDaoImpl.findByUser(String username)从数据库获取当前用户的现金流列表时，会发生异常。
为什么会发生此异常？我该怎么做才能阻止它？

The problem can be solved by adding the following property to persistence.xml:
<property name="hibernate.classloading.use_current_tccl_as_parent" value="false" />
