-----------------------------------------
https://github.com/apache/geode/pull/1209
> Can't get PDX objects using the new protocol
> --------------------------------------------
>
> Key: GEODE-4116
> URL: https://issues.apache.org/jira/browse/GEODE-4116
> Project: Geode
> Issue Type: Bug
> Components: client/server
> Reporter: Dan Smith
> Attachments: pdx_get_failure.diff
>
>
> The new client protocol doesn't correctly support PDX objects. The
> GetRequestOperationHandler directly calls region.get, which will
> *deserialize* the value stored in the region. The operation handler is
> expecting to get a PdxInstance back, but that will only happen if the cache
> has read-serialized set to true.
> I've attached a unit test that demonstrates this issue. If a region contains
> PDX objects and read-serialized is set to false (the default), the new
> protocol will throw exceptions if you try to get a value.
