However, _Gfsh_ never returns control to the user.
> GFSH simply hangs when the objects queried are not resolvable on the

> Key: GEODE-6430
> URL: https://issues.apache.org/jira/browse/GEODE-6430
> Project: Geode
> Issue Type: Bug
> Components: gfsh
> Reporter: John Blum
> Priority: Major
>
> If I run an OQL query in _Gfsh_ on data stored in a Region and none of the
> "application domain model classes" are on the system classpath of the server,
> or if I have not been deployed the application classes using the {{deploy}}
> command, then the `query` command in _Gfsh_ hangs!
> For example, suppose I am using Apache Geode to manage (HTTP) Session state
> using _Spring Session_. If I have the _Spring_ dependencies on the
> classpath, but none of the application classes on the classpath, nor
> "deployed" using the {{deploy}} command, then running the following query...
> {code}
> gfsh>query --query="SELECT session.id, attribute.key, attribute.value FROM
> /Sessions session, session.attributes attribute ORDER BY session.id ASC"
> {code}
> ... causes the shell to hang!
> In this use case, the users application creates a (HTTP) Session, stores
> application types in the Session and then persists the Session to GemFire.
> GemFire will successfully persist the Session containing the application
> types even though the application classes are not on the classpath,
> especially when serialized between the server and client, simply because
> GemFire does not need to deserialize the application class instances when
> storing the Session. Only if a Delta is applied to the Session, or the
> application objects stored in the Session are queried, will GemFire cause a
> deserialization and attempt to resolve the class types of the application
> objects. Otherwise, GemFire will retain the form of the object in which it
> received it.
> The only Exception/error present was in the Locator/Manager's log file...
