Review comment:
       Thing is I did leave that because I thought what if pdxType passed were 
nullptr, but that's not the way it's intended to be used, so I guess it would 
be best to force a coredump if pdxType is nullptr, right?

> *GIVEN*  **a  single server and locator cluster with 1 PdxSerializable class 
> registered, named Order
>    *AND* a geode-native client with 1 PdxSerializable 1 PdxSerializable class 
> registered, named Order
>  *WHEN* a Order object is tried to be serialized
>    *WHILE* the cluster is being restarted
> *THEN* a coredump happens due to PdxType=nullptr
> —
> *Additional information*. As seen by early troubleshooting, the coredump 
> happens because the pdx type is tried to be fetched from the PdxTypeRegist by 
> its class name, but the PdxTypeRegistry is cleaned up during serialization 
> given that subscription redundancy was lost.
