             Summary: When connection is closed, its server could be null
                 Key: GEODE-8485
                 URL: https://issues.apache.org/jira/browse/GEODE-8485
             Project: Geode
          Issue Type: Bug

            Reporter: Xiaojian Zhou


java.lang.NullPointerException

It's checking if need to create a new connection. In this context, it's 
possible that connection.getServer()==null

When we detected it, let it create a new connection. 

We catch all exception including NPE, and retry for all failure in dispatch.
