Hi, I’m attempting to migrate existing program from hibernate 5 to 6.0.0.Alpha9. Aware that spring/hibernate6 may not be compatible yet but giving it a try. I’m encountering some exception when trying to startup the application.

Exception

It seems to be hitting a nullpointer at “org.hibernate.type.internal.UserTypeJavaTypeWrapper.”.

Hi and thanks for testing. What kind of user type are you using? According to the stacktrace, it appears that this user type returns `null` from `org.hibernate.usertype.UserType#returnedClass`.

To my knowledge, I did not use any specific classes that implemented UserType. Probably could you point me to a direction I need to check for user type?

It’s hard to say, I would need to see the model. Maybe you can debug to the point where the exception occurs and try to figure out which field is causing this problem?

I might have found the cause for the exception. I have a created another small sample project to test and its giving the same exception

}

The above classes will give the same exception.

Issue seems to stem from the combination of @/Audited & @/Enumerated

when I only use @/Enumerated. Application is able to start up . Likewise, when i only use @/Audited & comment out the enumerated column, also able to start up.  
But when I use both @/Audited & @/Enumerated in the same class. It hits the exception.

Edit: Tried without @Enumerated annotation but still having a enum will cause the exception as well.

Any possible resolution for this?

I have found another weird issue whereby native queries with a list of paramters doesnt work.  
Eg. SELECT \* FROM table t WHERE t.column in (list parameters);

For the “list of parameters”, I fixed a bug in parameter list binding which is in Beta1. The specific bug related to passing a Collection as a parameter when that collection should be treated as a basic-type, but your error might be related.

I’ll try to format your posts above, but atm it is completely unreadable

For the enum issue, could you try Beta1 also? The mapping and resolution of basic types has changed significantly since Alpha9.

`@Enumerated` should be implied if the attribute is an enum fwiw.

Will try upgrading to Beta1. Aware Beta1 uses jarkarta.persistence.3.0.0. This means that our imports must be changes from

> import javax.persistence

to

> import jakarta.persistence

Will hibernate 6.0 be backwards compatible to jpa 2.2?

We will at some point release a JPA 2.2 variant as well, but for now this is JPA 3.0 only

May I know when will be JPA 2.2 be supported in Hibernate 6?
