> Project: Geode
> Issue Type: Bug
> Components: membership
> Reporter: John Blum
> Assignee: Bruce Schuchardt
> Priority: Major

> 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
