> Should a script desire to disconnect from one cluster and connect to another, it will fail without the continue-on-error option set.
> To reproduce:
> {noformat}
>     $> gfsh -e "start locator" -e "disconnect"
> (1) Executing - start locator
> ....
> Locator in [...] is currently online.
> [Details banner]
> Successfully connected to: JMX Manager [host=10.118.33.172, port=1099]
> Cluster configuration service is up and running.
> (2) Executing - disconnect
> Disconnecting from: 10.118.33.172[1099]
> Error occurred while disconnecting: null
> {noformat}
> Cause of NPE is in the disconnect command, currently belonging to ShellCommands.disconnect:199 in the line
> {noformat}
>           gfshInstance.setPromptPath(RegionPathConverter.DEFAULT_APP_CONTEXT_PATH);
> {noformat}
> which attempts to invoke a method on the member `reader`, which has not been initialized in headless mode.
