A serialized object is always wrapped by BinaryObjectImpl when it’s stored in memory in a specific cache partition or you access it from your application in a form of BinaryObject. However, when you transfer the object over the wire or put it into a persistent store (withKeepBinary property enabled) then only the byte array is used.
