启动Tomcat时出现Hibernate异常（升级到hibernate-3.5.0后）
升级到 Hibernate 3.5.0 后，使用 Web 应用程序启动 Tomcat 实例时出现以下异常：
org.hibernate.annotations.common.AssertionFailure: Fail to process type argument in a generic declaration. Type: class sun.reflect.generics.reflectiveObjects.ParameterizedTypeImpl
at org.hibernate.ejb.metamodel.AttributeFactory$PluralAttributeMetadataImpl.getClassFromGenericArgument(AttributeFactory.java:836)
at org.hibernate.ejb.metamodel.AttributeFactory$PluralAttributeMetadataImpl.getClassFromGenericArgument(AttributeFactory.java:833)
at org.hibernate.ejb.metamodel.AttributeFactory$PluralAttributeMetadataImpl.<init>(AttributeFactory.java:748)
at org.hibernate.ejb.metamodel.AttributeFactory$PluralAttributeMetadataImpl.<init>(AttributeFactory.java:723)
at org.hibernate.ejb.metamodel.AttributeFactory.determineAttributeMetadata(AttributeFactory.java:518)
at org.hibernate.ejb.metamodel.AttributeFactory.buildAttribute(AttributeFactory.java:93)
由于 Tomcat 启动时发生这种情况，我不知道在代码中查找何处以防止出现这种情况:-(
I'm getting the following exception when starting a Tomcat instance with my web app after upgrading to Hibernate 3.5.0:
org.hibernate.annotations.common.AssertionFailure: Fail to process type argument in a generic declaration. Type: class sun.reflect.generics.reflectiveObjects.ParameterizedTypeImpl
at org.hibernate.ejb.metamodel.AttributeFactory$PluralAttributeMetadataImpl.getClassFromGenericArgument(AttributeFactory.java:836)
at org.hibernate.ejb.metamodel.AttributeFactory$PluralAttributeMetadataImpl.getClassFromGenericArgument(AttributeFactory.java:833)
at org.hibernate.ejb.metamodel.AttributeFactory$PluralAttributeMetadataImpl.<init>(AttributeFactory.java:748)

at org.hibernate.ejb.metamodel.AttributeFactory.determineAttributeMetadata(AttributeFactory.java:518)
at org.hibernate.ejb.metamodel.AttributeFactory.buildAttribute(AttributeFactory.java:93)
As this happens on Tomcat startup, I have no idea where to look in my code to prevent that :-(
