Hello, we’re going to need more information if you want anyone to help you:

- when did you start getting this exception?
- in what context does the error occur?
- what do your mappings look like?

NPEs are usually caused by bugs. If you think this might be an Hibernate issue, please try to create a reproducer with our [test case template](https://github.com/hibernate/hibernate-test-case-templates/blob/master/orm/hibernate-orm-6/src/test/java/org/hibernate/bugs/JPAUnitTestCase.java) and if you are able to reproduce the error, create a new ticket in our [issue tracker](https://hibernate.atlassian.net/browse/HHH) and attach that reproducer. Note that 6.4 is also no longer supported, so I would strongly suggest upgrading to the [latest stable](https://hibernate.org/orm/releases) instead.

I have below properties in my legacy code are they correct for hibernate 6

spring.jpa.properties.hibernate.current\_session\_context\_class=org.springframework.orm.hibernate5.SpringSessionContext

spring.jpa.properties.hibernate.allow\_update\_outside\_transaction=true

Again, we cannot help you in any way with this limited information. Once again, please provide a reproducer test case and we might be able to look into what’s going on.

Please try to create a reproducer with our [test case template](https://github.com/hibernate/hibernate-test-case-templates/blob/master/orm/hibernate-orm-6/src/test/java/org/hibernate/bugs/JPAUnitTestCase.java) and if you are able to reproduce the issue, create a bug ticket in our [issue tracker](https://hibernate.atlassian.net) and attach that reproducer.
