Unable to connect to server from clients: session service is unresponsive (NPEs)
--------------------------------------------------------------------------------

                 Key: TEIID-601
                 URL: https://jira.jboss.org/jira/browse/TEIID-601
             Project: Teiid
          Issue Type: Bug
          Components: Server
    Affects Versions: 6.1.0
         Environment: Fedora 10, JBEDSP server snapshot from 13 May
            Reporter: Paul Nittel
            Assignee: Steven Hawkins
            Priority: Critical


I've set up a JBEDSP server on my laptop. I have been able to connect from the Console, but not really able to do much querying. This morning, I am no longer able to connect to the server (I tried SQuirreL and Console). 

Steve H. reviewed the server log and found the following to be central to the issue at hand. NOTE: I am NOT running this in  a cluster.
