> DirectMessageWriter cannot write nested collections.
> ----------------------------------------------------

>                 Key: IGNITE-2105
>                 URL: https://issues.apache.org/jira/browse/IGNITE-2105
>             Project: Ignite
>          Issue Type: Bug
>          Components: 1.4
>    Affects Versions: ignite-1.4
>            Reporter: Vladimir Ozerov
>            Assignee: Valentin Kulichenko
>            Priority: Blocker
>             Fix For: 1.5
>
>
> Steps to reproduce:
> 1) Run GridMessageCollectionTest in ignite-1.5 branch
> 2) Observe class-cast exception.
> The problem is caused by DirectByteBufferStreamImplV2 which is re-used across all nested
objects. 
> This class is stateful. When nested collection is written, instead of writing collection
element it writes element of another collection which is upper in call stack.
> Looks pretty critical for me.
