删除loadtimeweaver属性后，它工作正常。

< property name =loadTimeWeaver>

< bean class =org.faces.controller。 jpa.JpaLoadTimeWeaver/&GT;
< / property>

这个链接表明，尽管它已经很旧了，

I am working on a project with Hibernate JPA /spring.

It throws the following exception. After doing some reading I removed all the xml-apis from dependencies but it throws the same error. Any ideas ??

After removing the loadtimeweaver property it worked fine.

<property name="loadTimeWeaver">
<bean class="org.faces.controller.jpa.JpaLoadTimeWeaver"/> </property>

this is the link that shows that, although it is quite old it works
