Folks, I get this issue most of the times if I am shutting down the server when the dashboard is loaded on the console. The percentage of this error happening is more than 50% if the user is on the dashboard page.
To me this is a blocker?? This should affect all the products with dashboards, and this is not a dashboard specific issue, just that the frequency of the error is high on the dashboard page. In other words our graceful shutdown is not working for servlet transport. Even though fixing the the graceful shutdown could be bit tough, we should be able to get rid of the NPE.
