Compilation error: duplicate name for grouping and enum in ietf-routing.yang

Hi,

I tried to generate JAVA class from ietf-routing.yang (see http://www.netconfcentral.org/modules/ietf-routing), but the generated classes cannot compile, because grouping special-next-hop and enum special-next-hop have the same name, yang definition as follows. Could you solve the problem? Thanks!

grouping special-next-hop {
description
"This grouping provides the leaf for specifying special
next-hop options.";
leaf special-next-hop {
type enumeration {
enum "blackhole"

{ value 0; description "Silently discard the packet."; }

enum "unreachable"

{ value 1; description "Discard the packet and notify the sender with an error message indicating that the destination host is unreachable."; }

enum "prohibit"

{ value 2; description "Discard the packet and notify the sender with an error message indicating that the communication is administratively prohibited."; }

enum "receive"

{ value 3; description "The packet will be received by the local network device."; }

}
description
"Special next-hop options.";
}
} // grouping special-next-hop
