Anthony, I was able to reproduce the issue with a quite simple class
https://github.com/claudiu-balciza/GeodeDeserializationErrorPOC/tree/develop
the command line application above populates 3 entries of Class1 objects in the
DeserializationErrorPOC region
the region is created as follows:
gfsh> create region --name=DeserializationErrorPOC
--type=PARTITION_REDUNDANT_PERSISTENT --recovery-delay=10000
--disk-store=DataPersistence --enable-statistics=true
--eviction-action=overflow-to-disk
--compressor='org.apache.geode.compression.SnappyCompressor'
--redundant-copies=1
gfsh> describe region --name=DeserializationErrorPOC Name :
DeserializationErrorPOC Data Policy : persistent partition Hosting Members :
server1
Name : DeserializationErrorPOC
Data Policy : persistent partition
Hosting Members : server1
Non-Default Attributes Shared By Hosting Members
Type | Name | Value
--------- | ------------------ | ---------------------------------------------
Region | data-policy | PERSISTENT_PARTITION
| size | 3
| cloning-enabled | true
| disk-store-name | DataPersistence
| statistics-enabled | true
| compressor | org.apache.geode.compression.SnappyCompressor
Eviction | eviction-action | overflow-to-disk
| eviction-algorithm | lru-heap-percentage
Partition | redundant-copies | 1
| recovery-delay | 10000
The domain class is deployed on the server:

Also the application throws a “SpringBasedCacheClientApplication:
org.apache.geode.SerializationException: While deserializing query result”
exception if I try to execute repository.findAll().forEach((item) ->
System.out.println(item.toString()));

Thanks so much! The other thing that puzzles me here is that the value is
being deserialized at all—I thought we could just stream the serialized form
directly into the export file.
