Description

When running DeploymentMode CONTINUOUS or SHARED and connecting a client node with a different userVersion from the server nodes - IgniteAtomicLongs and IgniteAtomicReferences cannot be fetched directly from Ignite.

IgniteAtomicLong atomicLong = ignite.atomicLong("long", 0, false);
IgniteAtomicReference<String> atomicReference = ignite.atomicReference("reference", "", false);

It throws an Exception

SEVERE: Error deserializing job response: GridJobExecuteResponse [nodeId=b52607ba-b6d1-47bc-983c-380af8a679bd, sesId=f13d9c48c61-0fabe984-ecf1-4acf-84ac-3bdd478405f7, jobId=023d9c48c61-0fabe984-ecf1-4acf-84ac-3bdd478405f7, gridEx=null, isCancelled=false, retry=null]

It works if you use a compute job to fetch it.

long remoteLong = ignite.compute().call(() -> { return ignite.atomicLong("long", 0, false).get(); });
ignite.compute().call(() -> { return ignite.atomicLong("long", 0, false).incrementAndGet(); });
String remoteReference = ignite.compute().call(() -> { return ignite.atomicReference("reference", "", false).get(); });

I've attached a small reproducer project.
