Ok, I found that I can use binaryObject.deserialize() to get back the POJO. So, the only remaining question is:
When a cache does not have 'withKeepBinary' set, why ContinuousQuery can handle class versioning fine whereas ScanQuery cannot? Is that an expected behaviour?

I found that when I use a ScanQuery on that cache, result will be deserialized using OptimizedMarshaller; Ignite sends 'ordered' message using GridCacheQueryResonseEntry. Whereas if I use ContinousQuery, result will be deserialized using BinaryMarshaller. My problem is that ScanQuery won't be able to handle class versioning. Question: 1. I am using "keepBinary" and BinaryObject on the cache to avoid versioning related problem. Is that the recommended approach? Because it seems strange that "ScanQuery" and "ContinousQuery" have different behaviour. 2. What is the recommended way to convert BinaryObject into POJO? Ignite website talks about getting field of each object using 'BinaryObject.field()'. However, Ignite uses 'BinaryReaderExImpl implements BinaryReader' internally. How can I get a reference to that object?
