Chris Cranford ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%3Aea49f1db-ef91-4d96-8f3a-a939be8d2b1c ) You are right that the spec does not cover this issue, but the spec does not take into consideration the use case when you’d want to map a List , Set , or Map to a JSON column in the database or when you want to map a List entity attribute to a PostgreSQL ARRAY column type.

Currently, this issue affects the Hibernate Types project as, even if the basic attribute is a List , it’s still a basic attribute, not a parent-child association that can be used in a JOIN.

I will provide a PR to address this issue, and I’d appreciate if you take a look at it.
