> * Locators post version 1.12.0 when send out the Configuration to old version 
> locators
>  * Old locators are not able to interpret the null jarNames sent by the new 
> locators
>  * This causes a lot of NPEs in the old locators
>  * This clears out the jarNames in the configuration and if a server joins 
> the cluster and requests the cluster configuration from the oldest locator, 
> then it does not the jars deployed in the cluster.
