Details:
Empty animators caused a subtle bug in swf9 because of implicit coercion
in swf9:
In swf9, 'undefined' can only be used for the any-type ('*'), for any
other type 'undefined' is coerced to 'null'. This is a problem if you
intend to use strict typing, but then forget some casts. In this case,
the "attribute"-property was casted to String in some methods, but in
several methods it wasn't. And if you later use string concatenation
(here: "e_" + attribute), you may get "e_null" (coerced) or
"e_undefined" (not coerced).
