> NPE during CqStatusListener method invocation.

> Key: GEODE-1687

> Project: Geode
> Issue Type: Bug
> Components: cq
> Reporter: Anilkumar Gingade
> Assignee: Anilkumar Gingade
>
> When a connection relating to CQ is established or dropped, CqStatusListner
> is invoked to indicate connection/subscription status. This allows
> application to handle if all the subscription connection is lost for CQs.
> Looking at the code path for CqStatusListener there is a chance of NPE
> getting thrown in CqServiceImpl.invokeCqsConnected when CQ is executed using
> the Bridge loader interface (old way of client-server
> connection)....
> When a pool or bridge-loader connection is made or dropped, the code gets all
> the CQs; checks if the CQ is registered using that connection/pool name and
> invokes the CqStatusListner...
> The code to check if CQ is using the corresponding pool:
> Pool cqPool = cQuery.getCQProxy().getPool();
> If the CQ is getting executed using Bridge loader, the CqProxy for CQ is not
> set when its constructed; its set when it gets executed....During this time
> the call to cQuery.getCQProxy() could throw NPE.
