According to JPA 2.0 specification section 3.2.7.1, when merging a detached entity with lazy associations that haven't been fetched:
" The persistence provider must not merge fields marked LAZY that have not been fetched: it must ignore such fields when merging. " After merging an entity, will accessing one of the entities LAZY fields (that was previously not fetched) result in a lazy initialization error or will we try to fetch from the database?
