>             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].
