thanks to Angela for pointing that out.
while i reread the javadoc of Node.canAddMixin and think that it hasn't been adjusted to match the new behaviour of Node.addMixin... there is now a new issue (#787) asking for clarification. from my point of view canAddMixin should be symmetric to addMixin. if the EG decides that this shouldn't || must not be the case the javadoc should mention it. regards angela
