Review comment:
Ok, so I've been going throught the query engine code of the server and
finally located the problem.
As I feared org.apache.geode.cache.query.internal.Bag addAndGetOccurence
method uses mapGet on the different objects added, and PdxInstanceImpl hash is
not considering noJavaDomainClass attribute and neither is the equals operator
therefore all PdxInstanceImpl with the same hash that are equals as of equals
operator are not added but instead the previous existing copy inside bag is
duplicated.
Now the question, and here is where I need your help, is: "Is this a bug or
a feature?"
Because as of my point of view is a bug, but there might be many more
implications than the one I am able to see.

> Key: GEODE-8512
> URL: https://issues.apache.org/jira/browse/GEODE-8512
> Project: Geode
> Issue Type: Improvement
> Components: native client
> Affects Versions: 1.13.0
> Reporter: Mario Salazar de Torres
> Assignee: Mario Salazar de Torres
> Priority: Minor
> Labels: JsonFormatter, pull-request-available
>
> Within Java client, you can specify if the PdxInstance you want to create is
> a Java domain class or not, but this is not the case for geode-native C++
> client.
> Thing is that in order to implement JsonFormatter in C++ client, having this
> change is mandatory, otherwise creating PdxType's with __GEMFIRE_JSON
> classname will present some issues while using cquery's.
