Hello! That issue may be caused by different versionы of UserRegistrationInfoResponse class. serialVersionUID is used during deserialization to verify that the sender and receiver of a serialized object have loaded classes for that object that are compatible with respect to serialization.
You have disabled this check by having "private static final long serialVersionUID = 1L;". Please ensure that you do not use multiple versions of your class during dev/test. Maybe you have instances in cache with different set of fields, for example. Regards, -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
