Corba JNDI provider is broken

I tried to create an InitialContext for the Corba JNDI provider (COS naming service provider) and got the error "Exception in thread "main" org.omg.CORBA.OBJECT_NOT_EXIST:" This was working yesterday morning (svn update on Mon 20 Oct about 10am UTC) but after updating trunk in the afternoon it is now broken. Heres the factory and url I used:

properties.setProperty(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory");
properties.setProperty(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
properties.setProperty(Context.PROVIDER_URL, "corbaloc::localhost:3528/JBoss/Naming/root");
InitialContext ctx = new InitialContext(properties);

The new InitialContext call throws the following exception:

[java] Exception in thread "main" org.omg.CORBA.OBJECT_NOT_EXIST: ---------BEGIN server-side stack trace---------
[java] unknown oid
[java] ---------END server-side stack trace--------- vmcid: 0x0 minor code: 0 completed: No
