Your original post gave no indication that Node inherited from 
AbstractSet. Actually, you gave no indication of any inheritance 
structure, etc. The only way we could know what the problem was would be 
to either read your mind or to give a general, vague answer. Providing 
sufficient information to mention this would have precluded the whole 
debate.

That's why there's so much emphasis on the SSCCEs (short, 
self-contained, compilable code examples) in this newsgroup: if you can 
minimize the problem down to a self-contained solution that is small 
enough to include in a post, it gives all the information we need. And, 
often times, just trying to minimize it may lead you to the answer 
without needing to ask the question in the first place.
