> If use the Geode API to configure and bootstrap a Geode Server (along with an embedded Locator and Manager) from my IDE and happen to have the {{org.skyscreamer:jsonassert}} dependency on my CLASSPATH, then upon connecting to this server in _Gfsh_ and performing `{{list members}}`, I encounter a {{NoSuchMethodError}}:

> The problem ends up being that both [JSONassert|https://github.com/skyscreamer/JSONassert] and *Apache Geode* make use of incompatible versions of the Android JSON API under-the-hood. Apache Geode uses [Open JSON|https://github.com/tdunning/open-json] while JSONassert uses [Vaadin's Android JSON API|https://github.com/skyscreamer/JSONassert/blob/master/pom.xml#L52-L56], both of which were derived from the source, Google Android JSON API.
> So, because Apache Geode [imports and maintains this API as part of its own source|https://github.com/apache/geode/tree/rel/v1.7.0/geode-json/src/main/java/org/json], this incompatibility is likely to happen since JSONassert is a popular API to test REST-based Web Services.
> The ideal solution in this case would be to complete replace Open JSON with Jackson as a dependency.
