> Key: GEODE-5917
> URL: https://issues.apache.org/jira/browse/GEODE-5917
> Project: Geode
> Issue Type: Bug

> Gfsh query results show a mix of PdxInstances and
> PreferBytesCachedDeserializables with read-serialized=true
> A gfsh query on a partitioned region with pdx read-serialized=true shows
> results like:
> {noformat}
> shares | price | id | cusip | serializedValue |
> sizeInBytes | stringForm
