> When defining Geode Properties and using the API to start a Geode Server connecting to
an existing Locator, if the {{hostname}} of the Locator is incorrectly typed, Geode will throw
a {{NullPointerException}}.
> For instance, if I define Geode Properties using...
> {code:java}
> ...
>   private static Properties gemfireProperties() {
>     Properties gemfireProperties = new Properties();
>     gemfireProperties.setProperty("name", "SessionGeodeServer");
>     gemfireProperties.setProperty("log-level", LOG_LEVEL);
>     gemfireProperties.setProperty("locators", "loclhost[10334]");
>     gemfireProperties.setProperty("jmx-manager", "true");
>     gemfireProperties.setProperty("jmx-manager-start", "true");
>     gemfireProperties.setProperty("start-locator", "localhost[10334]");
>     return gemfireProperties;
>   }
>   private static Cache gemfireCache(Properties gemfireProperties) {
>     return new CacheFactory(gemfireProperties).create();
>   }
> ...
> {code}
> And, as you can see, I mistyped "localhost" as "loclhost" in {{gemfireProperties.setProperty("locators",
"loclhost[10334]");}}, this results in...
> {code:java}
> Exception in thread "main" java.lang.NullPointerException

the {{log-level}} to "error") I would possibly never have seen these warning messages...
