Then I am confused with the exception I got. Please bear with me.
I believe what happened was a client (with a new version of user class) trying
to deserialize an old object (an old version of user class) from Continuous
Query.
This was what happened base on the log:
1. GridCacheIoManager unmarshalled GridCacheQueryResponse
2. GridCacheQueryResponse unmarshalled one element in its bytes collection
3. BinaryMarshaller (internally GridBinaryMarshaller) was being used
1. It then found out that it needed to unmarshal an Optimized object
1. The Optimized object turned out to be a GridCacheQueryResponseEntry
and tried to unmarshal GridCacheQueryResponseEntry.val
1. Looks like we tried to unmarshall serveral 'Serializable'
objects along the way
OptimizedMarshaller is always used for all system type (unless it is
Binarylizable). I looked at the OptimizedObjectInputStream.java, I cannot find
any way to 'read object using BinaryMarshaller or BinaryReaderExImpl ' once we
are inside OptimizedObjectInputStream.readObject0().
Can I assume that BinaryMarshaller won't be used for any object embedded inside
GridCacheQueryResponse?
If I am correct, do you have any suggestion on how I can avoid this type of
issue? Hopefully I am wrong.
Thanks,
Calvin
Caused by: java.io.IOException: Unexpected error occurred during unmarshalling
of an instance of the class: java.time.Ser. Check that all nodes are running
the same version of Ignite and that all nodes have GridOptimizedMarshaller
configured with identical optimized classes lists, if any (see setClassNames
and setClassNamesPath methods). If your serialized classes implement
java.io.Externalizable interface, verify that serialization logic is correct.

Hello,
In that case, only 'createdTime' fall back to OptimizedMarshaller.
Thanks,
