@Embedded.Nullable returns as non-null for null collection property about spring-data-relational HOT 3 OPEN

Placing collections in an embeddable is somewhat problematic as the current code only checks values from the current row in ResultSet. To determine whether there are values, we would have to run a query to check whether there are values. Then run another query to fetch the actual rows. With a single property, all this can be done, but running multiple queries for multiple relationship properties is where it becomes problematic.

I agree this is a bug and we need to take care of it.

Maybe I am lost in the context, but the collection is part of the current row when it is an array column. So, no additional query should be needed.

The code imho already has all the information needed to return the correct null result for the embedded object, as it needed to fill all the null fields in it already.

You're right; I missed that the component type is String and, therefore, a simple type. In any case, we nee to fix the issue on our side.
