-------------------------------------------

             Summary: Binary marshaller does not preserve component type when deserealizing even basic array typed fields
                 Key: IGNITE-4331
                 URL: https://issues.apache.org/jira/browse/IGNITE-4331
             Project: Ignite
          Issue Type: Sub-task
          Components: binary
    Affects Versions: 1.8
            Reporter: Alexander Paschenko
             Fix For: 2.0


How to reproduce: try to deserialize *single* field having type of {{Byte[]}} or any other primitive wrapper type array. It will be deserialized as {{Object[]}} and won't be suitable even to set the same field's value again - metadata check on object building will fail as required ({{Byte[]}}) and given ({{Object[]}}) types won't match.

As agreed with [~vozerov], currently we're not fixing it. Probably will get back to this while working on 2.0 release.

Discovered by [~skozlov] while running SQL DML examples during 1.8 release QA process, exact reasons found by [~al.psc].
