Answer 1

java.lang.VerifyError: class org.hibernate.type.WrappedMaterializedBlobType overrides

final method getReturnedClass.()Ljava/lang/Class;

似乎你有不支持的Hibernate版本（或）它是classpath中的依赖jar。 See this jira如果有帮助的话。

Answer 2

使用http://www.jboss.org/tattletale检查您的类路径。根据此Hibernate forum条目，您还可以在类路径上拥有多个不兼容的Hibernate-xxx.jar库。

同样从我的检查中，这可能是安全管理器的问题，因为代码试图覆盖（遮蔽）标记为final的方法。因此，安全管理器会检测到可能尝试克服java安全措施（无法替换子类中的最终方法）。

检查你是否使用了不兼容的hibernate版本，因为这个类恰好来自hibernate源。
