Sorry missed this. This was an jdk7 javadoc patch. in jdk6 the javadoc 
hasn't said anything about this.
I thought about it, but there is not good solution to pass through the 
calls of hashCode and equals to the underlying Collection (List / Set / 
other custom Collection) without breaking symmetric while having
the Set and List implementations (both check if the other object is also 
a Set or List.

And all my other deduplication candidates i have seen are in the same 
category.
