> You are getting duplicated end nodes, but the paths are unique (as the
uniqueness you've chosen suggests). You could solve it by adding an
evaluator which filters duplicate end nodes for you:
new Evaluator()
{
Set<Long> ids = new HashSet<Long>();
public Evaluation evaluate( Path path )
{
return Evaluation.ofIncludes( ids.add( path.endNode().getId() )
);
}
}

Where did you get that link? The correct is
http://components.neo4j.org/neo4j-kernel/snapshot/apidocs/org/neo4j/kernel/Traversal.html#returnAllButStartNode(with
the added /snapshot)
