I have two entities named ‘Contact’ And ‘ContactCustomField’. They have 1:1 relationship between them. Both contact/and custom field has account_id which defined as a partition key. When we define such a mapping, startup fails with below NPE
----------------------| |-------------------------------|
Contact | -------> |. ContactCusotmField. |

I am able to replicate issue with a testcase as well. [HHH-16942] - Hibernate JIRA
