-----------------------------------------
Summary: __GEMFIRE_JSON PDX type has invalid PdxType
Key: GEODE-7794
URL: https://issues.apache.org/jira/browse/GEODE-7794
Project: Geode
Issue Type: Bug
Components: native client
Reporter: Matthew Reddington
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.
