----------------------------------

    Issue Type: Feature Request  (was: Bug)
      Assignee:     (was: Emanuel Muckenhuber)


This amounts to an incompatible behavior change to critical library, so it would only happen after very careful consideration.

> .. if you omit the second line of this snippet, that means call asList on an empty node (empty, not null of course), an IllegalArgumentException will be thrown. I think this behavior is not appropriate. It should rather return an empty list.
> If I picked the wrong component or assignee, fell free to change it :)
