             Summary: Chat demo - May cause NPE when disconnecting clients
                 Key: AMQ-4807
                 URL: https://issues.apache.org/jira/browse/AMQ-4807
             Project: ActiveMQ
          Issue Type: Bug
    Affects Versions: 5.9.0
            Reporter: Claus Ibsen
            Assignee: Claus Ibsen
            Priority: Minor
             Fix For: 5.10.0


After testing the 5.9 RC I played with the various demos, and the chat demo.

I opened a 2nd browser to login with a 2nd user, and did some chat.
I noticed in my console these WARN logs. Not sure if they happened when I disconnected a client, or something.
