NPE during generation of java binding for case list-grouping-choice

I get NPE when I try to generate java binding from this yang example:

module test-list-grouping-choice {
namespace "urn:foo";
prefix "foo";

revision 2014-10-29 {
}
list group {
key name;

leaf name

{ type string; }

grouping remote-user-remote-auth {
choice remote-user {
mandatory true;
leaf same-user

{ type empty; }
leaf remote-name { type string; }
}
choice remote-auth {
mandatory true;
leaf same-pass { type empty; }

leaf remote-password

{ type string; }

}
leaf remote-secondary-password

{ type string; }
}

container default-map { uses remote-user-remote-auth; }
list map {
key user;
leaf user { type string; }

uses remote-user-remote-auth;
}
}
}

Exception and debug snippet:
