----------------------------------------
Summary: NPE during CqStatusListener method invocation.
Key: GEODE-1687
URL: https://issues.apache.org/jira/browse/GEODE-1687
Project: Geode
Issue Type: Bug
Components: cq
Reporter: 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.
