Hibernate EntityManager working with Collections

I have an entity (InvalidAddress) with a many to one relationship with another entity (ServiceRequest). I am trying to add an InvalidAddress entity to the InvalidAddressCollection owned by ServiceRequest



I am getting a NPE because serviceRequest.getInvalidAddressCollection() is returning null when there are no related InvalidAddress entities. I know this makes sense but it seems like a waste to have to do this before I add any related entity to any collection



Is this very repetitive boiler-plate required when working with collections?

It would seem like the EntityManager should initialize the Collection and just return an empty list instead of a null list. Or is that up to me when I implement the getter on ServiceRequest?

Thanks for any advice.
