[Hawkular-dev] Alpha7 startup problem

[Van Dillon]

Thanks for the quick reply John.

I did the following:

1) Disabled the agent
2) Started the server successfully
3) Created a user with the Hawkular UI
4) Stopped the server
5) Enabled the agent and added the credentials for the newly created user
6) Started the server again

Now all seems to be working.
