             Summary: NPE if click on failed CDK server
                 Key: JBIDE-21613
                 URL: https://issues.jboss.org/browse/JBIDE-21613
             Project: Tools (JBoss Tools)
          Issue Type: Bug
          Components: cdk
    Affects Versions: 4.3.1.CR1
            Reporter: Alexey Kazakov


I ran my CDK server but it failed by timeout (it tool longer than the timeout to start the server).
When the server finally started (I saw it in the console) I clicked on the server in the server view to "restart" it. You don't need to start/stop the server. Just click on/select the server in the view:
