> Project: Geode
> Issue Type: Bug
> Components: serialization
> Reporter: Bruce Schuchardt

> Priority: Major
> Labels: pull-request-available
> Fix For: 1.6.0

> Recent changes in DataSerializableFixedID serialization have left CQ reply
> message handling in a bad state. When results are read they are deserialized
> into POJOs and this can cause queries to hang if the domain classes aren't
> available in the server. Even if they are it will hit performance because
> the objects are completely deserialized and then have to be re-serialized to
> be sent to clients.
> If the classes aren't available an exception like this will be thrown:
> {noformat}
> org.apache.geode.SerializationException: Could not create an instance of
> org.apache.geode.distributed.internal.streaming.StreamingOperation$StreamingReplyMessage
