我正在尝试将我们项目的 Hibernate 版本从4.3升级到5.2。我已经通过以下文档完成了升级所需的步骤

以及其他版本的升级文档。但是，在进行所需的更改后，我面临一些运行时错误。

我采用了一个非常简单的示例模型，在我的 EntityModel 中如下所示：

EntityMetamodel(cemployees_create:[Attribute(name=LastName, type=string [non-identifier]),Attribute(name=FirstName, type=string [non-identifier]),Attribute(name=BirthDate, type=timestamp [non-identifier] ]),Attribute(name=HireDate, type=timestamp [non-identifier]),Attribute(name=Photo, type=binary [non-identifier]),Attribute(name=ReportsTo, type=cemployees_create [non-identifier,association ]),Attribute(name=ReporteesArr, type=java.util.Collection(cemployees_create.ReporteesArr) [non-identifier,association])])

但是在5.2版中，当它试图在 AttributeFactory.java 中构建属性时，它会抛出以下异常：

java.lang.IllegalArgumentException: Expecting collection type [org.hibernate.type.BagType]
    at org.hibernate.metamodel.internal.AttributeFactory.determineCollectionType(AttributeFactory.java:937)
    at org.hibernate.metamodel.internal.AttributeFactory$PluralAttributeMetadataImpl.<init>(AttributeFactory.java:786)
    at org.hibernate.metamodel.internal.AttributeFactory$PluralAttributeMetadataImpl.<init>(AttributeFactory.java:767)
    at org.hibernate.metamodel.internal.AttributeFactory.determineAttributeMetadata(AttributeFactory.java:548)
    at org.hibernate.metamodel.internal.AttributeFactory.buildAttribute(AttributeFactory.java:77)
    at org.hibernate.metamodel.internal.MetadataContext.wrapUp(MetadataContext.java:213)
    at org.hibernate.metamodel.internal.MetamodelImpl.initialize(MetamodelImpl.java:220)
    at org.hibernate.internal.SessionFactoryImpl.<init>(SessionFactoryImpl.java:297)
    at org.hibernate.boot.internal.SessionFactoryBuilderImpl.build(SessionFactoryBuilderImpl.java:452)
    at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:710)

当它试图为 Attribute(name=ReporteesArr, type=java.util.Collection(cemployees_create.ReporteesArr) [non-identifier,association])])构建属性时，就会发生这种情况

只是想检查是否有人以前遇到过这个问题，或者是否有任何解决方案。同样的事情在 Hibernate 4.3 上也能正常工作

同时添加休眠实体映射文件：

<?xml version="1.0"?>
