Specification is not clear about null handling for Collections #118
Description
The specification document is clear about null serialization for Arrays (section 3.14.2) however it is not clear about nulls and collections.
Yasson by default omits javabean properties with null values during serialization, but treats collections same as arrays, resulting in preserving nulls for them in JSON document. Is that behaviour correct? If so can section 3.14.2 be updated to include collections?
