command "create class w extends V" gives error: Super-class V not exists

[atanaschristov]

version: orientdb-graphed-1.5.1

server started with server.sh
used console.sh to connect to the server

On clean install when I try to create class, which extends V or E, the server gives error. See the log bellow.

The interesting part of the bug is that after I create a regular class and try to create a vertex in it, of course an error appear, but after that I am able to create classes, which extends V and E

Bellow are the commands to reproduce the bug

Commads given on clean install:

orientdb> create database remote:localhost/test admin admin local
.....................
orientdb> create class w extends V

Error: com.orientechnologies.orient.core.sql.OCommandSQLParsingException: Error on parsing command at position #0: Error on parsing command at position #22: Super-class V not exists
Command: create class w extends V
------------------------------^
orientdb> create class wo 

Class created successfully. Total classes in database now: 9

orientdb> create vertex wo set name="test"

Error: com.orientechnologies.orient.core.exception.OCommandExecutionException: Error on execution of command: sql.create vertex wo set name="test"

orientdb> create class w extends V        

Class created successfully. Total classes in database now: 12

create the database as "graph":

create database remote:localhost/test admin admin local graph
