>             Project: Ignite
>          Issue Type: Bug
>          Components: thin client
>    Affects Versions: 2.7
>            Reporter: Sergey Antonov
>            Assignee: Sergey Antonov
>            Priority: Critical

> Scenario:
>  * Start server node with predefined cache and activate cluster.
>  * Connect thin java client to cluster
>  * Put entry to the cache with user defined key (custom class) from server node.
>  * Try get value from thin client by the same key. 
> Expected:
> Returns putted value
> Actual: 
> Returns null
> Reproducer:
> {code:java}
