List not empty when using getColumnValue("colName", ArrayList.class) on an empty column

[dnmd]

When using entry.getColumnValue("colName", ArrayList.class) on an empty column, it does not return an empty list as one might expect. But a list with one String element.

List<String> list = entry.getColumnValue("colName", ArrayList.class);

System.out.println(list.isEmpty()); // false
System.out.println(list.size()); // == 1

1. I don't know if this is intended or by design but I could not find any examples / known issues about it.
2. What would be a proper way to prevent such behavior? As I would expect an empty List, my guess is that it happens somewhere around here

We would have to add a switch for this behavior, because the legacy API
returns a Vector with one "" in it when a column value is "empty"
just like it does with an "empty" field. There's actually no such thing as
empty in Notes.
