Dan Florian resolved JBIDE-6966.
--------------------------------

    Resolution: Done


Looks like for some reason the DqpPlugin instance was null. I am now checking that during shutdown of DqpUiPlugin. Also added a ServerManager state variable since ServerManager shutdown could possibly be called by different threads.
