我们正在使用Spring ORM 4.2.1.RELEASE通过JPA与Hibernate进行交互。Hibernate
4.3.11.Final一切正常，但是当我们尝试升级到Hibernate
5时，在构造SessionFactory时会出现AbstractMethodError中断。

根据发行说明，Spring
4.2.1确实支持Hibernate5。检查Maven依赖树没有显示任何重复或过时的Hibernate或Spring版本。报告的特定行（https://github.com/hibernate/hibernate-
orm/blob/master/hibernate-
core/src/main/java/org/hibernate/internal/SessionFactoryImpl.java第278行）正在迭代hibernate集成器，但是我们不使用任何集成器，因此，集成器列表在逻辑上应为空（因此不能进行迭代）。

有谁知道这是spring的错误（或缺乏支持），还是我们做错了？
