Deserialization of List with one item

I am using GSON for JSON deserialization and so far it has been a great help.
But I am struggling with an issue with de serialization of List with generic 
and concrete types when the list contains only one element.

For example - 

public class Department {
    public String name;
    public String code;
}

public class Product {

        private List<String> attributes;
        private List<Department> departments;

        public List<String> getAttributes() {
            return attributes;
        }

        public void setAttributes(List<String> attributes) {
            this.attributes = attributes;

        public List<Department> getDepartments() {
            return departments;
        }

        public void setDepartments(List<Department> departments) {
            this.departments = departments;

    }
}

This works fine if either of my list attributes or departments contain more 
than one item in the list.
But if it contains only element in the list - I get an error saying - no valid 
JSON Array

Please help!
