Codegenerator emits lengthConstraints unnnecessarily, leading to a warning

org.opendaylight.yang.gen.v1.urn.opendaylight.params.xml.ns.yang.bgp.linkstate.rev131125.IsisAreaIdentifier contains the following code:

public static List<Range<Integer>> getLength()

{ final List<Range<Integer>> result = new ArrayList<>(); List<Range<Integer>> lengthConstraints = new ArrayList<>(); result.add(Range.closed(20, 20)); return result; }

Note that lengthConstraints is never touched, resulting in a warning being raised by Eclipse.
