>          Issue Type: Bug
>          Components: native client
>            Reporter: Matthew Reddington
>            Priority: Major

> The native client is built on the presumption that class name is unique. Since the introduction of __GEMFIRE_JSON, that is no longer the case. Where the logic presumes it can use cached deserialization rules in the form of a PdxType, looked up by name, this is no longer the case.
>  
> What we have observed is if a cache instance does not have a PdxType for a __GEMFIRE_JSON class instance, the first get and deserialization will succeed, but all subsequent gets will result in an empty PdxWrapper.
>  
> Steps to reproduce:
>   1) Instantiate an instance of Cache.
>   2) Put a PDX value with class name __GEMFIRE_JSON.
>   3) Instantiate a second instance of Cache.
>   4) Use this cache to make two consecutive gets of the PDX value. Inspect the results.
>  
> Observations:
>   1) The first get will succeed in returning an instance of PdxInstance with the expected fields and values as per step #2.
>   2) The second get will return a PdxWrapper of class name __GEMFIRE_JSON and a user object of null.
