Support empty lists in 2-Level nested collections #38

Closed jerolba closed 3 months ago

Serializing 

record Data(String name, List<Integer> ids) { }

If ids collection is empty, is serialized with null value instead of empty collection.

For 3-level collections was already fixed, but not reviewed for 2-level one
