Description

Reported by the user, simple program being run twice:

using (IIgnite ignite = Ignition.Start(config))
            {
                var cache = ignite.GetOrCreateCache<Guid, Data>(nameof(Data));
                cache.QueryContinuous(new ContinuousQuery<Guid, Data>(new Listener()));
        
                // Pressing any key in the console will add a value to the cache
                while (true)
                {
                    Console.ReadKey();

                    var entry = new Data() { Id = Guid.NewGuid(), Value = "a value" };
                    cache.Put(entry.Id, entry);
                }
            }

Causes exceptions on Java side:

For some reason Java tries to deserialize .NET value.
There is no exception on .NET side, but events are not delivered.
