create ks failure with latest github source

[Yang]

I pulled the latest code from
github 3e77792d31344be0253c89355c1d96ffe03c0659

and used my old commands to create a regular KS, and it failed.
quick debugging shows that the client hits an NPE somewhere.

am I missing some new mandatory args ?

Thanks
Yang
