Review comment:
For this particular case I'm accessing the elements by index using
`functionResults.get(i)` and `functionResults.get(resultsSize - 1)` within a
`for (int i = 0; i < resultsSize - 1; i++)` loop, so I need the check to avoid
any `IndexOutOfBoundsException`.

> Key: GEODE-3898
> URL: https://issues.apache.org/jira/browse/GEODE-3898
> Project: Geode
> Issue Type: Bug
> Components: querying
> Reporter: Juan José Ramos Cassella
> Assignee: Juan José Ramos Cassella
> Labels: configuration, gfsh
>
> When using the cluster configuration service, indexes created through {{gfsh
> define index}} + {{gfsh create defined indexes}} are not persisted to the
> cluster configuration service.
> Steps to reproduce:
> # Start a locator with {{enable-cluster-configuration-enabled=true}}.
> # Start a server with {{enable-cluster-configuration-enabled=true}}.
> # Create a sample region: {{gfsh create region --name=TestRegion
> --type=REPLICATE}}.
> # Define an index: {{gfsh define index --name=index1 --expression=value1
> --region=TestRegion}}.
> # Created the defined indexes: {{gfsh create defined indexes}}.
> # Restart the cluster.
> # Execute {{list indexes}}. The command returns no indexes.
